Installation Issues
When I tried installing minecraft 1.9pre-release 2 it said: Error

Could not find application.
 * Please list the steps you took Nightred 17:17, 30 September 2011 (UTC)

Crashing

 * If you have a stack or block of 'Block 97' (Silverfish block), putting the mouse over it while in the Inventory screen crashes the game with a 'Saving Chunks' screen. --ClassyCreeper15 15:30, 29 September 2011 (UTC) ClassyCreeper15
 * I can back this one up; additionally, it appears to only be a client error. When on an SMP server, if someone has block 97 in their inventory, mousing over it will crash them out, but no one else.  My guess is that it's related to the new tooltips added in 1.9 pre2.  It tried to load a tooltip for a block that doesn't have one. Thedarkfreak 07:13, 30 September 2011 (UTC)


 * Getting killed by an arrow, shot by a dispenser crashes the server. 89.0.78.67 16:40, 29 September 2011 (UTC) Zinnusl

When I create a new world it says "Switching Level" then it crashes.
 * What do you mean by 'crashes'? OS? Java version? --96.49.116.92 17:18, 29 September 2011 (UTC)
 * The Minecraft window instantly closes, it happens to me too.
 * Me too.
 * Me as well.


 * Deleting a Regular Survival World, after first Playing Hardcore, then Playing the Survival Mode you are going to delete, will cause a crash in the game. It is unknown if this has anything to do with Playing Hardcore mode(and dying in it) or if this happens upon deleting Regular Survival Worlds regardless of Hardcore Gameplay. This Crash occurs on SSP with Intel Mac OSX 10.6.8. and Java SE 6 64 bit ver. 1.6.0_26-b03-384. I can't seem to reproduce this bug, it might be a "first time" crash thing. Btw i died by drowning.


 * When you try to generate a world in either of the 1.9 pre-releases (any mode) your game closes.
 * I have not had this problem with either pre-release (neither client nor server). Can you supply any more information (console logs, OS, Java version)? — minrice2099 (talk - contribs) 22:44, 29 September 2011 (UTC)
 * I can't find my version number (it's the latest Java version) or console logs, due to problems with my computer, but I'm running Windows 7.


 * I got the same error and the game creates a text file with this in it:
 * A fatal error has been detected by the Java Runtime Environment:
 * EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000006db18170, pid=13416, tid=16212
 * JRE version: 6.0_15-b03
 * Java VM: Java HotSpot(TM) 64-Bit Server VM (14.1-b02 mixed mode windows-amd64 )
 * Problematic frame:

 * Java VM: Java HotSpot(TM) 64-Bit Server VM (14.1-b02 mixed mode windows-amd64 )
 * Problematic frame:
 * V [jvm.dll+0x328170]


 * i got the same error! it just closes, no text thing. windows 7, inspiron, chipset family graphix card, intel pentium, directx 10 or 9 i think... this is frustrating...


 * I had the same thing until I upgraded Java to 64 bit one then no more problem. 71.229.87.151 04:13, 30 September 2011 (UTC)
 * Same problem, except upgrading java doesn't help, and I cannot find any error logs. This is using the client, not the server.


 * When I try to change the volume of either the in-game music or sound, my game crashes by showing "Saving Chunks" for a second or two and then crashing (the way it crashes is it freezes showing the dirt background of the "saving chunks" screen). Don't know if I'm the only one experiencing this but it is really annoying because this means that the music and sound of the game is turned off and I can't get it back on without the game crashing. --Waendchen 21:53, 1 October 2011 (UTC)

Creative Mode General

 * When you hold right click on milk you will drink it
 * Probably not new, but confirmed here. — minrice2099 (talk - contribs) 20:15, 29 September 2011 (UTC)

When you left click a mob in Creative with wheat in your hand, the wheat will disappear. --Porygon27 20:16, 29 September 2011 (UTC)

You cannot play / check noteblocks by left-clicking them because they insta-break. If you right-click, it changes the note. --DaftasBrush 11:51, 02 October 2011 (UTC)

Gameplay
When holding a bushel of wheat, I right clicked to open a door. The door opened, but the wheat I was holding vanished. I'm guessing this is a product of the breeding stuff that was just added and, when I right clicked, it tried to use the wheat on the door to put it into "love mode". Would be kinda cool if we could breed doors. :P ~Markus talk 01:11, 2 October 2011 (UTC)
 * Unexpected Wheat Use
 * Probably due to the infinite items check. The code will occasionally check if the item you're holding is infinite and remove it if it is. --Wizjany 01:15, 2 October 2011 (UTC)

In Pre-release 2 (does not occur in Pre-release 1 (just re-downloaded to double check)) the redstone torches will burn out after a few cycles. Replacing the torches only temporarily fixes the problem as they burn out again after a few more on/off cycles.[ user: gnomefreak 2:39pm Oct1, 2011]
 * Redstone Torch Burnout
 * Tested on Pre1 and Pre2 CSP. Could not find any significant change in redstone torch burnout. A simple torch/wire 5-clock was stable; 3-clocks and 1-clocks were not. Unconfirmed. — minrice2099 (talk - contribs) 19:31, 1 October 2011 (UTC)
 * The circuits I was having problems with were 1 or 2 torch piston door types.
 * If you could point to a video of the setup or a set of images, I could try it myself. — minrice2099 (talk - contribs) 01:59, 2 October 2011 (UTC)

It appears that some biomes are changed in the way that their weather is switched, even in desert biomes, there is snow, also I have noticed that there is now snow appearing on water and on ice in these altered biomes... --LethalComboFilms 19:05, 1 October 2011 (UTC)
 * Snow on Water/Ice and Altered Weather
 * Did this happen in a world that was generated in some version of 1.8? It's possible (although I've never actually heard of this happening) that, since snow biomes weren't included in that version, that it is cold enough in some areas for snow to fall. Again I have nothing to back this up, and it's only a theory, but if biomes use a temperature/humidity system, this could possibly be the case. — minrice2099 (talk - contribs) 19:31, 1 October 2011 (UTC)

Mushroom Stew cannot be stacked, which is annoying since its my no.1 food thanks to the giant mushrooms (just find 1 normal, put some bone meal on it and you get >20) --0M9H4X 17:21, 30 September 2011 (UTC)
 * Mushroom Stew
 * I don't think that's a bug. Also exists in 1.8. --96.49.116.92 23:24, 30 September 2011 (UTC)
 * I wouldn't say that it's not a bug (double negative intentional); it's probably intended for all food to stack. It's just that mushroom stew replaces itself with an empty bowl when you finish it, so they would have to do something about putting the bowl in your inventory as well has do something about the case when your inventory is full. I wouldn't doubt it to implemented in a release or two. — minrice2099 (talk - contribs) 00:15, 1 October 2011 (UTC)

If you right click a Mooshroom with a stack of bowls, the stack is replaced by a single Mushroom Stew, and the rest of the bowls disappear. --68.151.22.70 01:08, 2 October 2011 (UTC)
 * Mooshrooms and Mushroom Stew

When placing a vine in front of another vine (right clicking with a vine while looking at one) will cause the vine to disappear. (It will be taken from you inventory but not appear in the world). EDIT: This does not occur ehen the vine you want to place yours on is growing on a leave-block. Confirmed it on Wood and Cobble though. --0M9H4X 20:29, 29 September 2011 (UTC)
 * Vines Bug

Fences do not block player movement for the entire block anymore, which is a feature i know but it doesnt work for fence gates. So when walking next to a fence, you will suddenly get stuck on the gate. --0M9H4X 20:15, 29 September 2011 (UTC)
 * Fence Gate Bug

When placing a nether rack fence next to a normal fence, they will not attach to each other. Although each type of fence will connect to a fence gate. Using the gate will allow you to attach the nether rack fence and normal fence together. Not sure if this was present in 1.9.1 or if it is a bug at all. --Throex 15:09, 29 September 2011 (UTC)
 * Fence Bug

Diagonal fences no longer block movement. --Fett0001 16:29, 29 September 2011 (UTC)

Pressure plates (stone and/or wood) can be attached to wooden "Fence" posts, can not be attached to "Nether Brick Fence" --71.193.183.45 18:59, 29 September 2011 (UTC)

Pressure plates on wooden "Fence" posts now activate (click) when you get next to them, do not activate when you stand on top of the fence. If the intent was just to create a hackish way to create a table, should the table really "click" when I approach it? --71.193.183.45 19:10, 29 September 2011 (UTC)

Wood fences connect to pumpkins.--46.146.148.202 11:25, 30 September 2011 (UTC)
 * Fences currently connect to (nearly?) every solid block. — minrice2099 (talk - contribs) 14:15, 30 September 2011 (UTC)

Fences can now be used as safe zones from mobs. For example, if you are in an abandoned mineshaft and a mob is chasing you, you can stand "inside" (right up against) a fence post and the mob can't get to you. --DetachableMonkey 11:31, 30 September 2011 (UTC)

Glass panes don't seem to appear correctly when placed under stairs. The top border of the glass panes is glitchy when the camera moves.
 * Glass pane glitch

Enderman seem to disappear after touching water. If you hit them, have them follow you to water, instead of teleporting away from it, they just disappear. Anyone else confirm? --Throex 15:46, 29 September 2011 (UTC)
 * Enderman Bug
 * May have just teleported to a cavern underground.


 * Enderman sometimes not taking damage from the day. Feature or bug? Maloncanth 02:26, 30 September 2011 (UTC)

You cannot sprint for more than 30 consecutive seconds regardless of hunger or game mode (creative/survival). Fair chance it isn't a bug, but I didn't notice this before, so I'm putting it here. — minrice2099 (talk - contribs) 21:03, 29 September 2011 (UTC)
 * Sprinting

You also move at insane speed if you jump while sprinting on ice. The speed is not conserved when you land (IE: You only get superspeed while you're in the air)121.74.239.222 06:01, 1 October 2011 (UTC)
 * Big confirmation on this one. As opposed to barely being able to clear a four-block gap on dirt, sprint-jumping on ice makes a four-block jump easy. With enough practice and time, I may even be able to clear a five-block gap. — minrice2099 (talk - contribs) 07:37, 1 October 2011 (UTC)

You take 2 and 1/2 hearts damage after teleporting. --rush247 21:58, 29 September 2011
 * Ender Pearls
 * Pretty sure this isn't a bug. Although I can't seem to find it, I'm sure I saw some Mojang staff mention this. Regardless, it would be a pretty major and obvious bug to just make it through to release. — minrice2099 (talk - contribs) 14:12, 30 September 2011 (UTC)

Not entirely unexpected, if you throw the ender pearl at close range to an object or at a thin object you may teleport into it or glitch through it. Both occurred occasionally while testing with a Glass Pane. 192.168.0.41 16:09, 30 September 2011 (UTC)

Made a map in the Nether and it duplicated my first Overworld map. Haven't repeated the process yet, but intend to.--Therealzerobot 14:23, 30 September 2011 (UTC)
 * Are you sure you didn't just shift click when creating the map? This creates a copy of map_0. — minrice2099 (talk - contribs) 14:12, 30 September 2011 (UTC)
 * No, indeed I am not sure! I've gotten into the habit of shift-clicking when creating a thing. I will try again and be sure not to do so. Thanks.--Therealzerobot 14:23, 30 September 2011 (UTC)

When you place a block of TNT over a dropped item the item will not eject out of the TNT. if the dropped item is sticking out of the TNT (but less than half way) the item will appear to be black, as though it is suffocating. 67.163.251.154 21:22, 30 September 2011 (UTC)
 * TNT Bug

Redstone Blocks only light up when you click on them with your pick. If you're mining a different block and move the cursor onto the Redstone, it doesn't activate. --Supermathie 01:46, 1 October 2011 (UTC)
 * Redstone Block activation


 * You can enter a minecarts and boats from unlimited distance and sometimes through blocks. --82.131.88.142 14:10, 2 October 2011 (UTC)
 * You sure you weren't playing in creative mode? This is typical of Entity interaction in creative. — minrice2099 (talk•contribs) 14:13, 2 October 2011 (UTC)


 * When im feeding animals to breed them I go down to one wheat left and it doesnt disappear no matter how much i feed them Archerofyail 17:59, 2 October 2011 (UTC)

Hardcore Mode

 * Furnace is not working properly, cannot use sticks and such as fuel.
 * I just used sticks to cook 2 pork chops in hardcore mode (however, my furnace was invisible when I placed it). --81.11.229.108 22:02, 30 September 2011 (UTC)


 * Hostile mobs not spawning in hardcore mode.
 * If Difficulty Mode is set to Peaceful in options before you create a new Hardcore game, monsters will not spawn. You must exit your hardcore world and change the difficulty in another game before monsters will spawn in your hardcore world. 174.61.145.17 19:22, 29 September 2011 (UTC)
 * Confirmed -- 85.226.98.234


 * The PrintScreen button is not taking pictures/ screenshots of the game, or is not allowing them to be posted in a programs like Skype. only found on this dificulty.

Graphical (GUI)
How do you post pictures on this Wiki? If you see this screenshot I took, you'll see a graphical glitch with the XP bar:imgur.com/qWXHl Shouldn't we have a graphical bugs section? EDIT: I just created a new section for graphical bugs. By the way, I am running on Mac OS 10.7.1
 * This bug seems to appear when you start the game right after the update, it will disappear when you collect EXP.91.21.113.57 15:40, 29 September 2011 (UTC)Centrophobia

(this explains Centrophobia's post in text format) There is a bug with the experience bar were if you used 1.9pre1 and gained a lot of experience, there would be multiple bars, once you kill yourself in water, it will be back to normal Micheal 17:17, 29 September 2011 (UTC) This problem also effects Windows 7 users Micheal 17:23, 29 September 2011 (UTC)

Now that F5 looking at yourself is back, you can see your inner face graphic punch though the outer "hat" layer of the skin when up close and crouching.

The leaves of lily still do not have a name in the inventory. Now an empty textbox is shown when the cursor flows above them. Hope I chose the topic right. Dhalek 19:13, 29 September 2011 (UTC)


 * The character preview in the inventory is darker when you have a status effect. The preview immediately lightens when the effect goes away. This does not effect the appearance of the player outside of the inventory. (screenshot) — minrice2099 (talk - contribs) 21:00, 29 September 2011 (UTC)


 * Labels of the item is much darker than in previous version and is highlighted with a purple line. May be a change of design.
 * Can't say for sure (as always), but it certainly appears too intentional (and polished) to be a bug. — minrice2099 (talk - contribs) 14:35, 30 September 2011 (UTC)


 * Oceanic horizon flickers.--46.147.53.110 14:10, 30 September 2011 (UTC)


 * Chests can get stuck in the Open animation position if you open while holding food. May only be SMP.  The animation has your food bob twice, once for opening the chest and once in an extra animation.  Chest will be stuck in the "open" position clientside.  Takes a few tries to reproduce online, can't get it to happen in single player. --Taedirk 02:58, 1 October 2011 (UTC)

Lighting

 * I had a "normal" memory crash but when I reloaded blocks around me had changed. They were in the same basic configuration but my workbench "turned into" a stone block and empty space turned into charcoal. Most odd is that the torch I placed before the crash was nowhere to be found but the light was still there. This is in single player survival Sparkalyn 04:26, 30 September 2011 (UTC)
 * when the sun came up the "light" went out. Sparkalyn 22:55, 30 September 2011 (UTC)


 * XP Orbs

In darkness XP Orbs don't show any colour or "glowing" effect.

--Supermathie 01:44, 1 October 2011 (UTC)

Memory/CPU
Here is the link to that topic:
 * Whereas the lag from 1.9pre1 has been all but dissipated, the game will still cause an almost insane amount of cpu usage and causes the temperature of the processor to climb to dangerous heights. Some people on the forums have suggested that it has something to do with the JAVA IO thread priority of the world generation found in the bn.class. This bug is found across all platforms and processor types, although it might not be as noticeable on newer machines.


 * on the mac version of minecraft i seem to have some kind of memory leak, when i start playing with the graphics set to fancy i get 50-60 fps, this slowly declines until its about 10-20 fps. when i go to options and switch to fast graphics, exit the options menu and then go back to the options menu to set it back to fancy my fps goes back to 50-60. can anyone confirm this? Jap0jum 12:11, 30 September 2011 (UTC)
 * A memory leak (or even general memory usage) shouldn't have any effect on graphics performance; that's all CPU/GPU related. Regardless, I haven't noticed any excessive CPU usage/framerate drops. Have you tried playing with Advanced OpenGL turned on? Depending exactly what you're doing, that can provide a significan't boost in performance (at least it did on my Mac). There's a very big chance that this is just another threading related problem that seems to plage all of the pre-releases. — minrice2099 (talk - contribs) 14:23, 30 September 2011 (UTC)


 * I have a pretty nice computer, but it appears as though Minecraft is having problems with CPU usage mine ramped up past 88%, which is way to high!
 * This seems to be a general problem with the pre-releases. It will probably go away with the official release. — minrice2099 (talk - contribs) 14:53, 30 September 2011 (UTC)

Mobs

 * [!] Chickens can walk through fences and Doors. Try to hold wheat outside of a fence box of chickens, as they try to follow you they will walk straight through the fence or door.  Maybe most to all blocks in general. Bloodyjabs 04:50, 30 September 2011 (UTC)


 * Normal Spiders can attack the player out in daylight in Hardcore mode. Kyle8497 15:49, 29 September 2011 (UTC)
 * They always have been able to do so - if they see you while it is dark out, they will lock on and follow you for as long as possible -regardless if it becomes daylight


 * Mooshrooms and Cows can interbreed, creating a child that can be either mob, intentional?
 * yeh this is strange and it produces a cow? What???????71.174.254.138 04:17, 1 October 2011 (UTC)


 * All passive mobs don't follow you when wheat is selected.
 * Works fine for me, all mobs follow me. --Throex 16:29, 29 September 2011 (UTC)
 * Pigs do, sheep and cows don't. Was in CSP. --96.49.116.92 16:38, 29 September 2011 (UTC)
 * I was in CSP when testing it as well. I never came across cows, but sheep and pigs followed me everywhere. --Throex 16:39, 29 September 2011 (UTC)
 * Tested in CSP as well. Cows (and Mooshrooms) followed me just fine, though I could only seem to get two "wild" ones to follow at once. When they bred, the offspring would then follow as well. — minrice2099 (talk - contribs) 17:30, 29 September 2011 (UTC)


 * To Make breed two same colored sheeps don't take a colored sheep.


 * In creative I can make Snow Golems in the desert and they don't melt.


 * Animals "held" by wheat will stop moving if you get out of follow range so long as you continue holding the wheat. — minrice2099 (talk - contribs) 17:30, 29 September 2011 (UTC)


 * Don't know if this is suppose to be the case but Endermen spawn in daylight and teleport every second. When one looks at them they scream and teleport far away instead of attacking. Anyone else get this?
 * Seems to be on purpose. During the day they do their thing as normal yet when you get within a certain radius they teleport away from you. With no teleport animation it looks like they are just glitching.

-when I tested this, I had chickens die
 * Somme passive mobs (maybe only chicken) seems immune to a creeper explosion.


 * Swamp grass don't spawn animals ! I have an island of swamp grass(dark green grass), with no trees, lit with torches. No animal spawn there anymore since I removed the trees. --Psycommando 23:51, 30 September 2011 (UTC)


 * Not really a glitch, but villagers have a random walking pattern which means that after a few minutes, most of them have left the village.


 * So many creepers spawning that the game is slowed to a crawl. Hundreds and hundreds of creepers.

Sound
Opening chests still does not have any sound. Maybe it's intentional because I think I remember chests were silent in 1.7.3 and before, but in 1.8.1 the sound of opening a door was played when opening a chest. Dhalek 19:16, 29 September 2011 (UTC)
 * This is almost certainly related to the pre-release nature of the game. Some sounds aren't properly packaged with the jar. — minrice2099 (talk - contribs) 19:22, 29 September 2011 (UTC)

Music discs seem to play extremely quietly, I had to set sound to 0, music to 100 and crank my speakers while standing right next to a jukebox. Really if your standing right beside it, the music playing should be louder than distant pistons, overpowering everything else. Darkbrewery 01:09, 30 September 2011 (UTC)
 * This isn't a problem for me. The volume seems appropriately proportioned to other sounds in Minecraft. Is there a chance that it could be an issue with the audio library/decoder/drivers on your system/platform? My knowledge on these technical aspects is passing at best. — minrice2099 (talk - contribs) 01:13, 30 September 2011 (UTC)
 * music disks play under "sound" not "music", make your sound on 100% and try it again. this may fix your problem --Wally
 * Confirmed Jukebox audio is tied to sound setting, not sure of reasoning behind this, since jukebox music mutes the in game music anyway. Darkbrewery 01:23, 30 September 2011 (UTC)
 * Makes sense, though. "Music" has no recognizable source; "sounds" come from a recognizable location. — minrice2099 (talk - contribs) 01:34, 30 September 2011 (UTC)

Spawning
Animals (I saw only pigs though) will spawn on the tree branches inside the leaves of large trees
 * Maybe not a new bug, but it's confirmed here (screenshot). — minrice2099 (talk - contribs) 18:42, 29 September 2011 (UTC)


 * Usually one kind of animals is prevalent significantly around player's spawn point.--46.146.186.33 16:48, 2 October 2011 (UTC)

Water
the first time I spawned in my minecraft 1.7 world with 1.9 (in 1.8 chunks), i die instantly when the breathing bar is up, my health doesn't decline, I just die instantly, this only happened once, it is back to normal thereafter Micheal 17:13, 29 September 2011 (UTC)

Weather

 * Snow now spawns on top of minecart rails- Did this used to happen? not sure if this is a bug. 71.227.74.87 22:24, 29 September 2011 (UTC)
 * The snow replaced my rails. They're gone.  Pretty sure that's a bug.  Also, it's snowing in my swamp.  Not sure if that's a bug, but it seems like one to me. 99.106.123.0 16:46, 2 October 2011 (UTC)


 * If you look up while it's snowing, you can see that it isn't snowing on the block you're standing on.
 * This is more a graphical bug than anything. It's an unfortunate side-effect of how snow (and rain, although it is less obvious) is actually rendered in-game. This also is nothing new; I'm pretty sure it's been this way since weather was introduced. — minrice2099 (talk•contribs) 14:18, 2 October 2011 (UTC)

Snow kills crops and destroys all that is not fully a block (like crops and rails)It also makes a layer of snow on water without turning it to ice. coppeerboy--Coppeerboy 21:47, 2 October 2011 (UTC)

= Confirmed =

Biomes
Big trees that spawn can't naturally retain their shape. Braking one outer leaf can start a chain reaction of deterioration.


 * May not be a bug: Trees that grow from saplings in swamp-biomes will not grow vines on them unless placed manually by the player. So if you farm some wood in a swamp, it will destroy the unique look of that biome (which I really like, thats why i care) --0M9H4X 20:38, 29 September 2011 (UTC)

The problem with large areas of ocean generated abruptly without transition at the edge of certain biomes is still there. --Axnjaxn 23:05, 29 September 2011 (UTC)


 * May not be present in 1.9 pre 2 - I wasn't able to reproduce the world from the same seed. On the other hand, deleting the ocean chunks in a map editor and allowing Minecraft to generate new chunks yielded more ocean. --Axnjaxn 03:01, 30 September 2011 (UTC)
 * Are you certain that the land chunks aren't also supposed to be ocean under the 1.9 code? You're not running around in a 1.8 world, are you? Because that would create that exact effect if you were. Moleculor 07:31, 30 September 2011 (UTC)

Creative Mode
You will punch mobs through several layers of blocks before removing any block in front of you. That is not a bug, but rather a feature :P --Ratman150 00:35, 3 October 2011 (UTC)

golden apple has a new texture pressing e in the inventory, but has the old texture when outside the inventory. also when thrown away it has the old texture. --Wally

Graphical (GUI)
http://www.minecraftwiki.net/wiki/File:HCMerror.jpg I have noticed that no matter what game mode is set, survival, hardcore or creative when you click "More world options" you will see on the bottom left "World is deleted upon death". Pretty sure this is a bug, considering that it is displayed even with hardcore mode off. --Throex 15:01, 29 September 2011 (UTC)

If you have a single piece of wheat in your hot bar and then right click on a mob, the wheat will not vanish from the hotbar and can be used over and over, the wheat will then be unable to be stacked and if thrown on the ground will not be able to be picked up.

Definitely the case in survival, you can also spawn infinite amounts of wheat by rightclick-dropping wheat in your inventory.
 * I can confirm this. I have the exact same issue. --Obi-Wahn 23:43, 29 September 2011 (UTC)
 * I can also confirm this.
 * I Came here to report this very same bug It also makes it so that you can't pick up any other wheat, or stack any wheat. It ruins harvesting.- Zellman: 1/Oct/2011

In the 1.9 pre-release, when you feed wheat to a mob while holding only 1 wheat, it causes that wheat to become infinite. You may also use right click to drop the wheat from your inventory and it will create multiple wheats on the ground for you to pick up.
 * Wheat
 * This is similar to above but also confirmed.

Non-livestock mobs sometimes respond in strange ways to wheat. Snow-golems will target you and follow you like normal when wielding wheat - but their targetting includes attacking you.

Snow-golems appear to attack each other instead of breed when attempting to feed them wheat, although they were surely not meant to be able to breed.

Snow Golems become aggressive when wheat is held.
 * Confirmed. Causing a "hurt" animation while no longer holding wheat will stop it from attacking you. — minrice2099 (talk - contribs) 17:30, 29 September 2011 (UTC)

Wolves (neutral and hostile) don't breed but show hearts like normal when fed wheat.

Other mobs may react oddly also. 4.244.150.233 17:13, 29 September 2011 (UTC)

Items
After breeding with wheat the wheat that was used is corrupted and can multiply on the workbench.

stop does not save chunks
The Minecraft Server cannot shut down cleanly and always results in loss of data when you do so! The server does not save the world when you close it due to the threaded chunk-saving. Because the thread that saves chunks is marked as a daemon thread, it is interrupted when you give the 'stop' command to the server, meaning any unsaved chunks are lost forever.

Tree leaf blocks not sent to client
When in the same chunk as a newly grown tree the blocks are not always sent to the client. Only unloading the cached chunk and re-loading it (E.G. Move very far away or teleport or reload client) are the blocks sent to the client. In 1.9pre1 (untested in pre2) the blocks were still present on the server side and behaved as an invisible barrier.

Ender Pearl
Using an ender pearl to teleport disconnects from the server for "hacking?".
 * Are you running an updated server? --Ianweller 16:22, 29 September 2011 (UTC)
 * ^Thats propably due to a plugin installed used against cheaters or excessive laggers. Its most likely not been updated to know about ender-pearl-teleporting so it thinks youre hacking. –The preceding unsigned comment was added by 0M9H4X (Talk . Please sign your posts with
 * I've addressed this problem on the ender pearl page, the "hacking" kick is triggered when player movement speed is above 10 blocks in distance in too short a time. --Wizjany 20:26, 29 September 2011 (UTC)
 * Absolutely confirmed as a bug running on an up-to-date (1.9pre2) vanilla server (locally). The pearls can be thrown and did damage as expected, but appeared to have no other effect until I actually moved. Then, depending on how far they were thrown, I was either teleported (which gave "Player moved wrongly" warnings to the console) (if thrown close) or kicked from the server (if thrown far) with the message "You moved too quickly :( (Hacking?)". — minrice2099 (talk - contribs) 20:38, 29 September 2011 (UTC)

Achievements
The Sniper Duel achievement still doesn't work. I built a pole to mark the 50 block distance and killed a skeleton there with arrows. The loot clearly lay behind the mark but I didn't get the achievement. And yes, I already have the Monster Hunter achievement. --Obi-Wahn 07:47, 30 September 2011 (UTC)
