            <title>[MC-11834] &quot;[SEVERE] Item entity # has no item?&quot; is spammed in the console and items appear as stone for invalid IDs or on initial drop</title>
                <link>https://bugs.mojang.com/browse/MC-11834</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;The Server is spammed with &lt;tt&gt;Item entity &lt;b&gt;number&lt;/b&gt; has no item!?&lt;/tt&gt; until it crashes. ~~It is the spawners because it stops when i break them. The spawners are custom and spawn armour and weapons. A copy of the spawner is in the attachments and a crash report.&lt;/p&gt;
&lt;hr /&gt;
&lt;p&gt;Confirmed for 13w41b with the following command, in a command block:&lt;/p&gt;
&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;/setblock ~ ~1 ~ minecraft:mob_spawner 1 replace {EntityId:Item,SpawnData:{Health:5,Age:0,Item:{id:7,Damage:0,Count:1}}}&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;Observe the spam in the Development Console of the launcher, or the server console if you perform this on a server.&lt;/p&gt;

&lt;p&gt;The message is now of the form:&lt;/p&gt;

&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;Client&amp;gt; [02:10:41] [Client thread/ERROR]: Item entity 9740 has no item?!&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;Marcono says:&lt;/p&gt;

&lt;p&gt;Like I &lt;a href=&quot;https://bugs.mojang.com/browse/MC-11834?focusedCommentId=255940&amp;amp;page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-255940&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;wrote already&lt;/a&gt;, the problem is the &lt;tt&gt;getEntityItem()&lt;/tt&gt; method (MCP 1.8 name). Minecraft expects it to be &lt;tt&gt;null&lt;/tt&gt; when no item data is stored but this method is required to return an &lt;tt&gt;ItemStack&lt;/tt&gt; for rendering (else the client will crash). Because of this currently it returns a new &lt;tt&gt;ItemStack&lt;/tt&gt; if the stored &lt;tt&gt;ItemStack&lt;/tt&gt; is &lt;tt&gt;null&lt;/tt&gt; (and prints the &quot;Item entity # has not item?!&quot; error message).&lt;/p&gt;</description>

                            <comment id="524388" author="pokechu22" created="Sun, 10 Mar 2019 03:24:57 +0100"  >&lt;p&gt;This issue was &lt;em&gt;technically&lt;/em&gt; fixed in 1.11 (=&amp;gt; 16w32a, the first snapshot); the message is no longer logged.  However, the fix results in removing the items clientside (&lt;a href=&quot;https://bugs.mojang.com/browse/MC-111978&quot; title=&quot;Item entities turn invisible when dropped on the ground&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-111978&quot;&gt;&lt;del&gt;MC-111978&lt;/del&gt;&lt;/a&gt;) which is a bit worse.&lt;/p&gt;

&lt;p&gt;I&apos;m resolving this as fixed since &lt;em&gt;technically&lt;/em&gt; it is fixed, in that there is no longer log spam or a stone item appearing.&lt;/p&gt;

&lt;p&gt;I&apos;m also going to clarify this issue to refer &lt;em&gt;only&lt;/em&gt; to newly spawned items or invalid items displaying as stone or and spamming the log.  (And as a very belated response to &lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=Lolmewn&quot; class=&quot;user-hover&quot; rel=&quot;Lolmewn&quot;&gt;Lolmewn&lt;/a&gt;&apos;s comment: &lt;tt&gt;cocoa&lt;/tt&gt; wasn&apos;t an item but only a block; it was only dye back then and spigot, being spigot, named dye ink sac.  That&apos;s what &lt;em&gt;your&lt;/em&gt; issue was, and it wouldn&apos;t apply in 1.13+.}}&lt;/p&gt;

&lt;p&gt;Whatever crash was referenced is presumably separate and likely relates to old behavior with forcing invalid items to render; that crash report doesn&apos;t seem to exist anymore.  There&apos;s also comments saying that the crash was modded only, so I think it&apos;s probably best to just completely exclude it.  And this ticket was first created in a pre-1.8&lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/help_16.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt; era where you could use block IDs for all items, even invalid ones; that hasn&apos;t been a thing for a while.&lt;/p&gt;</comment>
                            <comment id="517542" author="miwob" created="Thu, 7 Feb 2019 20:02:45 +0100"  >&lt;p&gt;Is this still an issue in the most recent versions (currently that is &lt;b&gt;1.13.2&lt;/b&gt;, or the latest snapshot &lt;b&gt;19w06a&lt;/b&gt;) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.&lt;/p&gt;</comment>

                            <comment id="325307" author="lolmewn" created="Sun, 14 Aug 2016 15:09:08 +0200"  >&lt;p&gt;I&apos;d like to comment that this happened to me too in Multiplayer. It seems to happen when spawning an item that doesn&apos;t exist (apparently). &lt;br/&gt;
I am using Spigot 1.10.2, which has a Material enum containing the &apos;COCOA&apos; material. When spawning this item this error starts to pop up. &lt;br/&gt;
I&apos;d also like to add that /give &amp;lt;me&amp;gt; cocoa results in &quot;There is no such item with name minecraft:cocoa&quot;.&lt;/p&gt;</comment>

Also, this bug is very annoying and I get it even in singleplayer. Does it only crash servers or singleplayer too?&lt;/p&gt;

&lt;p&gt;And finally, what causes this?&lt;/p&gt;</comment>

I&apos;m not exactly sure what to put here, but here&apos;s a paste of what my launcher said while I was playing:&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;error&quot;&gt;&amp;#91;20:27:04&amp;#93;&lt;/span&gt; &lt;span class=&quot;error&quot;&gt;&amp;#91;Client thread/ERROR&amp;#93;&lt;/span&gt;: Item entity 18391 has no item?!&lt;br/&gt;
&lt;span class=&quot;error&quot;&gt;&amp;#91;20:27:04&amp;#93;&lt;/span&gt; &lt;span class=&quot;error&quot;&gt;&amp;#91;Client thread/ERROR&amp;#93;&lt;/span&gt;: Item entity 18391 has no item?!&lt;br/&gt;
&lt;span class=&quot;error&quot;&gt;&amp;#91;20:27:28&amp;#93;&lt;/span&gt; &lt;span class=&quot;error&quot;&gt;&amp;#91;Client thread/ERROR&amp;#93;&lt;/span&gt;: Item entity 18569 has no item?!&lt;br/&gt;

&lt;p&gt;I&apos;m pretty sure this happened only while I was just mining some gravel, coal or iron. I&apos;ve searched around for this issue and it seems to possibly be from when item entities stack together. &lt;br/&gt;
Just a note, this was in completely vanilla minecraft, no add-ons/mods or server plugins, just plain vanilla singleplayer.&lt;/p&gt;</comment>

&lt;p&gt;1) This problem can be caused by a plugin trying to spawn a non-spawnable item stack.   IE a plugin tries to spawn Material.wall_sign or Material.melon_stem (there are a BUNCH more)  these are items that players aren&apos;t &quot;allowed&quot; to hold thus they become invalid and typically get rendered as smooth stone when they are actually dropped in the world.&lt;br/&gt;
2) Every time one of these non-spawnable items gets &quot;dropped&quot; in the world it will cause this error at least once.  Often times it will constantly spam until the offending item is picked up and /clear is run on the player holding the item.&lt;br/&gt;
3) If you have a plugin that spawns random items from minecraft into your world that is causing this problem contact the plugin&apos;s author and have them add this little bit of code to their plugin to fix the issue.&lt;/p&gt;

&lt;p&gt;You must have essentials installed and the plugin will need to hook essentials. (the plugin guys know how to do this)&lt;br/&gt;
          ItemStack is = new ItemStack(Material_To_Spawn);&lt;/p&gt;

&lt;p&gt;          MetaItemStack metaStack = new MetaItemStack(is);&lt;br/&gt;
           if(!metaStack.canSpawn(theirplugin.getES()))  &lt;/p&gt;
{ 
             //System.out.println(&quot;Unspawnable item: &quot; + is.getType().name());
            //do whatever they need to do, eg: return/continue/break etc.
            }

Minecraft expects it to be &lt;tt&gt;null&lt;/tt&gt; when no item data is stored but this method is required to return an &lt;tt&gt;ItemStack&lt;/tt&gt; for rendering (else the client will crash). Because of this currently it returns a new &lt;tt&gt;ItemStack&lt;/tt&gt; if the stored &lt;tt&gt;ItemStack&lt;/tt&gt; is &lt;tt&gt;null&lt;/tt&gt; (and prints the &quot;Item entity # has not item?!&quot; error message).&lt;/p&gt;</comment>

                            <comment id="255840" author="marcono1234" created="Fri, 16 Oct 2015 16:37:31 +0200"  >&lt;p&gt;The reason for this bug in 1.8 (recompiled with MCP): (Please add this completely or partwise to the description)&lt;br/&gt;
When the &lt;tt&gt;getItemEntity()&lt;/tt&gt; method is called and the value of the &lt;tt&gt;Item&lt;/tt&gt; tag is &lt;tt&gt;null&lt;/tt&gt; (does not exist or stores the value &lt;tt&gt;null&lt;/tt&gt;), it prints the error message and return a new &lt;tt&gt;ItemStack&lt;/tt&gt; however it does not modify its own &lt;tt&gt;Item&lt;/tt&gt; tag. This means that the next time the method is called it will print again the error and so on. A possible fix would be to also set the returned &lt;tt&gt;ItemStack&lt;/tt&gt; as item stack of the item entity.&lt;/p&gt;

&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeHeader panelHeader&quot; style=&quot;border-bottom-width: 1px;&quot;&gt;&lt;b&gt;Possible fix (1.8 using MCP)&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;/**
 * Returns the ItemStack corresponding to the Entity (Note: &lt;span class=&quot;code-keyword&quot;&gt;if&lt;/span&gt; no item exists, will log an error but still &lt;span class=&quot;code-keyword&quot;&gt;return&lt;/span&gt; an
 * ItemStack containing Block.stone)
 */
&lt;span class=&quot;code-keyword&quot;&gt;public&lt;/span&gt; ItemStack getEntityItem()
{
	ItemStack var1 = &lt;span class=&quot;code-keyword&quot;&gt;this&lt;/span&gt;.getDataWatcher().getWatchableObjectItemStack(10);

	&lt;span class=&quot;code-keyword&quot;&gt;if&lt;/span&gt; (var1 == &lt;span class=&quot;code-keyword&quot;&gt;null&lt;/span&gt;)
	{
		&lt;span class=&quot;code-keyword&quot;&gt;if&lt;/span&gt; (&lt;span class=&quot;code-keyword&quot;&gt;this&lt;/span&gt;.worldObj != &lt;span class=&quot;code-keyword&quot;&gt;null&lt;/span&gt;)
		{
			logger.error(&lt;span class=&quot;code-quote&quot;&gt;&quot;Item entity &quot;&lt;/span&gt; + &lt;span class=&quot;code-keyword&quot;&gt;this&lt;/span&gt;.getEntityId() + &lt;span class=&quot;code-quote&quot;&gt;&quot; has no item?!&quot;&lt;/span&gt;);
		}

		ItemStack defaultItemStack = &lt;span class=&quot;code-keyword&quot;&gt;new&lt;/span&gt; ItemStack(Blocks.stone, 1);
		&lt;span class=&quot;code-keyword&quot;&gt;this&lt;/span&gt;.setEntityItemStack(defaultItemStack);
		&lt;span class=&quot;code-keyword&quot;&gt;return&lt;/span&gt; defaultItemStack;
	}
	&lt;span class=&quot;code-keyword&quot;&gt;else&lt;/span&gt;
	{
		&lt;span class=&quot;code-keyword&quot;&gt;return&lt;/span&gt; var1;
	}
}
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;Eventually the contructor of the &lt;tt&gt;EntityItem&lt;/tt&gt; class should be changed as well to make sure that always a non-&lt;tt&gt;null&lt;/tt&gt; value is set as EntityItemStack. (In my tests that did not work very well)&lt;/p&gt;</comment>

&lt;p&gt;Here is the results from testing version 1.8.7:&lt;/p&gt;

&lt;p&gt;Singleplayer: The spawner does not cause anything to appear in the console, but &quot;/summon Item&quot; causes ~4 messages of &quot;&lt;span class=&quot;error&quot;&gt;&amp;#91;Server thread/ERROR&amp;#93;&lt;/span&gt;: Item entity # has no item?!&quot;.&lt;/p&gt;

&lt;p&gt;Singleplayer (open to LAN): Same as Singleplayer.&lt;/p&gt;

&lt;p&gt;Multiplayer Server: The spawner does not cause anything to appear in the console, but &quot;/summon Item&quot; causes the server log to be spammed with &quot;&lt;span class=&quot;error&quot;&gt;&amp;#91;&amp;lt;time&amp;gt;&amp;#93;&lt;/span&gt;&lt;span class=&quot;error&quot;&gt;&amp;#91;Server thread/ERROR&amp;#93;&lt;/span&gt;: Item entity # has no item?!&quot; and the client log to be spammed with &quot;[&amp;lt;time&amp;gt;][Client thread/ERROR]: Item entity # has no item?!&quot; (different value to server thread). &lt;br/&gt;
The server continues to be spammed if the player logs out from the server. The client still gets spammed upon joining the server. The spamming stops when the item is either picked up, despawns.&lt;br/&gt;
Stopping and restarting the server causes the spamming to stop.&lt;/p&gt;</comment>
                            <comment id="233678" author="theelectricgamer" created="Wed, 8 Jul 2015 16:42:46 +0200"  >&lt;p&gt;@Qi-rui Chen - By spams the console, do you mean it creates multiple messages when you run the command multiple times? And also, your summon command creating an error message is not a bug as you never assigned it an item while the command used elsewhere in this thread has a valid item.&lt;/p&gt;</comment>

I can also confirm &quot;/summon Item ~5 ~ ~&quot; (relative co-ords to make sure you don&apos;t pick the item up) still spams the console on 1.8.7.&lt;/p&gt;</comment>

&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;The reason for the &quot;Item entity # has no item?&quot; error seems to be a missing or invalid Item id:&lt;/p&gt;

&lt;p&gt;I am playing SMP on 1.8.1 with a friend, and I am having trouble everytime I activate doors using pressure pads, go through a portal, ride a horse etc. I lag out and sort of rubber band between different locations and my friend says I appear to be standing still. I get the following messages in my Game Output (see below), the times of which correlate to these laggy events.&lt;/p&gt;

&lt;p&gt;I don&apos;t have any custom spawners or anything. Is there anything I can do or is this still not understood?&lt;/p&gt;

&lt;p&gt;Cheers&lt;/p&gt;

I&apos;ve only received these bug reports twice, every other time it either freezes the computer screen, reboots the computer without errors (as if starting up for the first time), or crashes the computer (which is set to reboot, but it&apos;s registering as a crash and sending to me to the safemode options window). I&apos;ve set it up to collect memory dumps on crash and I can&apos;t get Windows to register these crashes as an event (can&apos;t get a single memory dump out of it, kernel or otherwise).&lt;/p&gt;

&lt;p&gt;Please fix! This renders the game unplayable.&lt;/p&gt;</comment>

Maybe worth mentioning that I&apos;ve made a clean install for 1.8, to see if it solves my lag issues. Well, it doesn&apos;t. Found out about this error instead.&lt;/p&gt;</comment>

I wonder if the wrong items are coming out when blocks are broken. I&apos;ve reported another error, where I noticed the coincidence: &lt;a href=&quot;https://bugs.mojang.com/browse/MC-71837&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://bugs.mojang.com/browse/MC-71837&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Broken wheat briefly showed up as smooth stone. And the errors contained here happened around the same time. Perhaps it&apos;s not always visually possible to see the bug happening, but maybe the errors contained here (&lt;a href=&quot;https://bugs.mojang.com/browse/MC-11834&quot; title=&quot;&amp;quot;[SEVERE] Item entity # has no item?&amp;quot; is spammed in the console and items appear as stone for invalid IDs or on initial drop&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-11834&quot;&gt;&lt;del&gt;MC-11834&lt;/del&gt;&lt;/a&gt;) are being thrown BECAUSE of the bug contained in &lt;a href=&quot;https://bugs.mojang.com/browse/MC-71837&quot; title=&quot;Harvested Wheat Briefly Shows as Stone &quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-71837&quot;&gt;&lt;del&gt;MC-71837&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

It&apos;s pretty ridiculous, really. On multiplayer however, this issue does NOT crash the game but does spam the console. &lt;/p&gt;

&lt;p&gt;*&lt;b&gt;EDIT&lt;/b&gt;*&lt;br/&gt;
By fullscreening i mean, for example, opening or quitting minecraft or CS:GO or any other game for that matter&lt;/p&gt;</comment>

So this happens always that a Spawner tries to spawn an Item.&lt;/p&gt;

&lt;p&gt;Command used:&lt;br/&gt;
/setblock ~ ~1 ~ minecraft:mob_spawner 1 replace {EntityId:XPOrb,SpawnData:{Value:0,Riding:{id:&quot;Item&quot;,Item:{id:5,Damage:0,Count:1}}}}&lt;/p&gt;</comment>

So the issue could be in that it is not summoning an item properly.&lt;/p&gt;</comment>

                            <comment id="123455" author="ddrkhat" created="Thu, 5 Dec 2013 23:01:28 +0100"  >&lt;p&gt;This can be resolved by properly formatting your Summoned Item&lt;/p&gt;

&lt;p&gt;/summon Item ~ ~2 ~ &lt;/p&gt;
{id:1,Age:5900}
&lt;p&gt; (Stone with 10s of life - spews tons of Item Entity has no item?!&lt;/p&gt;

&lt;p&gt;/summon Item ~ ~2 ~ {Item:&lt;/p&gt;
{id:1}
&lt;p&gt;,Age:5900} (Stone with 10s of life - does NOT)&lt;/p&gt;

&lt;p&gt;The difference between these two items is that the item spawned has a tag Item: Not FULLY sure why this resolves the issue, but it works for me.&lt;/p&gt;</comment>

Haven&apos;t yet checked if it also occurs serverside. Doesn&apos;t seem to be causing server-side issues, but some people are complaining about occasional random severe stutters, which may or may not be related.&lt;/p&gt;

I have a world with about 50-100 different item spawners with age set to 5999 so they despawn immediately, even when I fly far far away from all the spawners so none of them is activated and I don&apos;t get error messages any more, I still have memory up to 2000MB and a lot of lag.&lt;/p&gt;</comment>
                            <comment id="114166" author="wolfiemario" created="Wed, 23 Oct 2013 16:41:46 +0200"  >&lt;p&gt;Confirmed for 1.7.1.&lt;/p&gt;

&lt;p&gt;It&apos;s worth noting that this will happen in an invalid dropped item from 1.6.4 is encountered in 1.7.1:&lt;/p&gt;

&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;

Client&amp;gt; [10:31:27] [Server thread/ERROR]: Item entity 373 has no item?!
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;That spams and lags the server and clients until the item is collected. Fortunately, I think the item can still naturally despawn.&lt;/p&gt;

&lt;p&gt;But yes, definitely confirmed for spawners as well.&lt;/p&gt;</comment>

I used item spawners everywhere to spawn items with age set to 5999 on top of a pressure plate to trigger redstone clocks. Because I don&apos;t want a laggy world caused by thousands of commands firing in one tick. So now I just made the spawner spawn XPOrb. Though sometimes you just want to spawn items. Then connect a command block to the pressure plate that spawns an xporb riding an item, that way the spawner still doesn&apos;t trigger the pressure plate as long as there are too many items near&lt;/p&gt;</comment>

&lt;p&gt;Observe the spam in the Development Console of the launcher, or the server console if you perform this on a server.&lt;/p&gt;

&lt;p&gt;The message is now of the form:&lt;/p&gt;

My memory goes up and up and up but without the spawners it stays around 100MB whereas it went all the way up to 3000MB first&lt;/p&gt;</comment>

This shouldn&apos;t be too hard to fix, I remember it didn&apos;t occur in 1.3&lt;/p&gt;</comment>
                            <comment id="96727" author="wolfiemario" created="Fri, 2 Aug 2013 16:21:57 +0200"  >&lt;p&gt;The message is generated every time the item in the cage needs to be refreshed. It needs to be refreshed any time it either successfully spawns at least one item, or fails to spawn an item because too many are nearby. It also needs to be refreshed when the chunk containing it is first loaded.&lt;/p&gt;

&lt;p&gt;It should be noted that this message also spams the player&apos;s console, which is pretty annoying now that the launcher makes this visible in vanilla.&lt;/p&gt;</comment>
                            <comment id="96707" author="jespertheend" created="Fri, 2 Aug 2013 14:50:53 +0200"  >&lt;p&gt;Hmm makes sense, but when it isn&apos;t active because there aren&apos;t players in the spawn range the item is still visible but It doesn&apos;t give the message. Can you explain that?&lt;/p&gt;</comment>
                            <comment id="96690" author="wolfiemario" created="Fri, 2 Aug 2013 13:28:07 +0200"  >&lt;p&gt;Confirmed for 1.6.2.&lt;/p&gt;

&lt;p&gt;From what I can tell, the error is caused by the spawner itself, and not the entities it spawns. Or, more accurately, it occurs when the spawner tries to render an item spinning in its cage. It first constructs the entity without its item data, causing the error, and then fills in the missing SpawnData, which is why the issue occurs once per refresh of the spinning cage entity.&lt;/p&gt;</comment>
                            <comment id="92155" author="cblondeboy" created="Wed, 17 Jul 2013 07:09:31 +0200"  >&lt;p&gt;Got it.  So this is an issue with the spawning of an item feature itself.  It does allow for the item to be spawned in in that manner.  &lt;/p&gt;

&lt;p&gt;And that makes sense for the sethbling structure spawner v2 because if you go deep into the nbt tags, it does spawn an item entity (sandstone i believe, however i dont think that matters).&lt;/p&gt;</comment>
                            <comment id="91996" author="jespertheend" created="Tue, 16 Jul 2013 22:18:57 +0200"  >&lt;p&gt;According to Gerrard it is not just one variable, it is caused by the fact that an item is spawned using a spawner and not dropped on the ground using q or breaking a block or killing a mob. Because when you use sethblings filter (which copies all the tags) you still get this message.&lt;/p&gt;</comment>
                            <comment id="91894" author="cblondeboy" created="Tue, 16 Jul 2013 19:34:06 +0200"  >&lt;p&gt;If someone could go through an isolate each variable, we would be able to tell what is actually making the issue, not that it is just the spawners.&lt;/p&gt;</comment>

I should try that sometime and then delete every tag one by one to see which one I should keep.&lt;/p&gt;</comment>
                            <comment id="91834" author="wolfiemario" created="Tue, 16 Jul 2013 14:18:55 +0200"  >&lt;p&gt;You are supposed to add tags defining what type of item it is.

-Age:5999&lt;br/&gt;
-Pos&lt;/p&gt;</comment>
                            <comment id="87986" author="cblondeboy" created="Wed, 10 Jul 2013 05:20:02 +0200"  >&lt;p&gt;I believe that this has something to do with the unintended properties that we are using with the spawners, in my case, the manipulation of the t variable may be the issue (using seth blings structure spawner v2).  However, I do not understand the issue while using the item entity spawner.  &lt;/p&gt;</comment>

Same outcome as HiFolksImAdam, the Development Console in the launcher shows the error messages in SP, but there&apos;s no noticeable performance loss.&lt;br/&gt;
Starting an MP server with the map works perfectly until a player logs in. The error messages are then printed to the console and memory usage then climbs to the max and the server crashes.&lt;/p&gt;</comment>

&lt;p&gt;It did not, however, noticeably lag the game like it did in multiplayer.  &lt;/p&gt;</comment>

For each of the custom spawners in my world, it outputs the error message twice.  The message also appears to be coming from both the spawner blocks and spawner minecarts.&lt;/p&gt;</comment>

My world has a couple custom spawners, which from all accounts seem to be causing the issue, and severely lags the server.  However, there are no such issues playing the same world in SinglePlayer.  The server.log is posted above.&lt;/p&gt;</comment>

Anyways, no crash, I simply noticed the log entries after exiting my session and was curious and searched the tracker and then found this bug entry. Just thought I would share my experience.&lt;/p&gt;</comment>

I just closed my game after playing for about an hour and saw this message in the new launcher window I didn&apos;t close when I started. It occurred about 20 times near the start of my game. All I did during the game was dig a fort, place a furnace and used it, placed some chests and used them, and made a farm. I can&apos;t recall what I was doing at the exact time the messages were spammed though. These messages are the only ones out of the ordinary inbetween the saving messages from pausing the game. It&apos;s possible it was the furnace I used and this message was when a fuel was still burning without items.&lt;/p&gt;</comment>

Unless nobody else can reproduce it? I&apos;ve had it on several servers on different computers.&lt;/p&gt;</comment>
                            <comment id="55833" author="wolfiemario" created="Wed, 20 Mar 2013 17:39:39 +0100"  >&lt;p&gt;I&apos;ve added a new schematic in case OP&apos;s schematic did not work.&lt;/p&gt;

&lt;p&gt;Steps to reproduce:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Import the &quot;itemsPirate.schematic&quot; into your world. This schematic is designed to randomly spawn various rapidly-despawning items, and succeeds in doing so. All of these items are vanilla-compatible. It was originally made for a custom level I added to a copy of SethBling&apos;s Super Craft Bros map, so some of the items may be familiar to some people here. I should also note that SethBling&apos;s own spawners also caused this issue.&lt;/li&gt;
	&lt;li&gt;Start a vanilla 1.5 server, and go near the spawner.&lt;/li&gt;
	&lt;li&gt;Observe that the console is spammed with messages of the form
&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;
&lt;pre&gt;[SEVERE] Item entity # has no item?!&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;where # is a number which continuously increments.&lt;/p&gt;&lt;/li&gt;
	&lt;li&gt;Observe that the items are still spawned as intended.&lt;/li&gt;
&lt;/ol&gt;

Crash : Invalid because of too less memory&lt;br/&gt;
Spamming: Please provide &lt;b&gt;exact&lt;/b&gt; steps to reproduce.&lt;/p&gt;</comment>
                            <comment id="55706" author="wolfiemario" created="Wed, 20 Mar 2013 03:35:57 +0100"  >&lt;p&gt;Why is this closed as invalid? I&apos;m able to reproduce it, sans the crashes. As item spawners are a vanilla feature, they should not be spamming the console like this.&lt;/p&gt;

&lt;p&gt;EDIT: I should note, OP&apos;s crash report seems to indicate a mod item, &quot;CrimTopaz&quot;, outside the ordinary item ID range.&lt;/p&gt;

&lt;p&gt;On the other hand, I am getting messages of the form&lt;/p&gt;
&lt;div class=&quot;preformatted panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;preformattedContent panelContent&quot;&gt;
&lt;pre&gt;[SEVERE] Item entity 64 has no item?!&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;with legitimate, vanilla-supported item spawners. The number just keeps incrementing; I&apos;ve had it climb into the millions before. It makes traversing the server.log tedious. It also makes it difficult to communicate with players via the console; their chat and your own quickly get shunted off the screen.&lt;/p&gt;</comment>
                            <comment id="53293" author="kumasasa" created="Thu, 14 Mar 2013 23:38:35 +0100"  >&lt;p&gt;You should - at least when you make such experiments - start Minecraft with the default launcher to allocate enough memory.&lt;/p&gt;
&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;
&lt;pre class=&quot;code-java&quot;&gt;JVM Flags: 0 total; 
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;your JVM has only 256 MB - that is way too less.&lt;/p&gt;
