I noticed this back on 1.14.x, but always forgot to report this,
When setting the item in player's hand to null when using the PlayerInteractEvent crashes the server with this error:
[21:54:00] [Server thread/ERROR]: Encountered an unexpected exception java.lang.AssertionError: TRAP at net.minecraft.server.v1_15_R1.ItemStack.checkEmpty(ItemStack.java:86) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.ItemStack.setCount(ItemStack.java:865) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.ItemStack.add(ItemStack.java:869) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.ItemStack.subtract(ItemStack.java:873) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.ItemBlock.a(ItemBlock.java:64) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.ItemBlock.a(ItemBlock.java:24) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.ItemStack.placeItem(ItemStack.java:161) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.PlayerInteractManager.a(PlayerInteractManager.java:481) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.PlayerConnection.a(PlayerConnection.java:1250) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.PacketPlayInUseItem.a(PacketPlayInUseItem.java:27) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.PacketPlayInUseItem.a(PacketPlayInUseItem.java:1) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.PlayerConnectionUtils.lambda$0(PlayerConnectionUtils.java:19) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.TickTask.run(SourceFile:18) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.IAsyncTaskHandler.executeTask(SourceFile:144) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.IAsyncTaskHandlerReentrant.executeTask(SourceFile:23) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.IAsyncTaskHandler.executeNext(SourceFile:118) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.MinecraftServer.aZ(MinecraftServer.java:917) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.MinecraftServer.executeNext(MinecraftServer.java:910) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.IAsyncTaskHandler.awaitTasks(SourceFile:127) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.MinecraftServer.sleepForTick(MinecraftServer.java:894) ~[spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at net.minecraft.server.v1_15_R1.MinecraftServer.run(MinecraftServer.java:827) [spigot-1.15.jar:git-Spigot-f39a89e-73698cf] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_201]
The code I used to test:
@EventHandler private void onTest(PlayerInteractEvent event) { Player player = event.getPlayer(); if (event.getHand() != EquipmentSlot.HAND) return; if (event.getAction() != Action.RIGHT_CLICK_BLOCK) return; player.getInventory().setItemInMainHand(null); }
If I have a tool (ie: a diamond sword) in my hand, click, everything is find.
If I have a block (ie: grass block) in my hand, click, the server crashes.
I included my test plugin to test this out (excuse the name its the same test plugin I use for everything)
Does this happen on 1.14.4? Yes
Does this happen in vanilla? Can't test (due to it's a plugin issue)
Does this happen in CB? Yes, same crash
