NMS IndexOutOfBoundsException from World Deletion

So yes another issue.. Basically what causes it is I teleport all players out of the world then delete the world and this crashes the server with the following error: http://pastebin.com/fhypKBzi

I am unsure as to why this is happening. There is no other entities in the world. Mobs cannot spawn and all players are teleported out of the world. Also, all drops are cleared before the world is deleted.

I can show you the code for what exactly is happening, however, it is a bit hard to understand at first with reading exactly what all the methods do.

Anyways, any ideas?

 

It looks like the server is trying to do the game tick (that is, progress time forward one step) after you've already deleted one of the things the server needs in order to do the game tick in that world. I can't be more specific without code.

 

Did you unload chunks or make sure they were unloaded when deleting? Might help to do so. I'm not any professional when it comes to worlds, chunks, and stuff though.

 

Okay so basically this is what happens when a player dies:

• Checks to see if the player is in an arena
• Checks to see if the arena is running
• Ensures the person who killed the player is in the same world as the player who died
• Fires an arena specific death method (Code)
  • If the arena match is over THEN (Code)
    • Set the arena to not run
    • Teleports the players to another world
    • Records any stats that need to be recorded
    • Removed all the players from the arena
    • Unloads the world
    • Deletes the world

The problems occur only when the match ends.

 

Make sure to Bukkit.getServer().unloadWorld(world, false);

 

I forgot to add in the list that I also unloaded the world Anyways.. I also do that

 

Try unloading the world without deleting it and see if you get the same error.

 

Okay so this is interesting.. the plugin gets through all the steps with no error and then the error occurs after this in the PlayerDeathListener

Code:java

if(!arena.isRunning())
{
System.out.println("9");
return;
}
System.out.println("10");

Nothing happens after that method. In other words, 10 is never printed to the console.

Also, if I comment out this method from running when the match is over the error disappears.

Code:java

public void endTeleportAction()
{
//later should teleport all players to the realm gates or whatever we end up calling them
//Location loc = Bukkit.getWorld("spawn").getSpawnLocation();
ZoneWorld postWorld = ZoneWorldAPI.getWorld(getPostGameSpawn().getWorld());
System.out.println("123");
if(postWorld != null)
{
System.out.println("11");
if(!world.isLoaded())
{
world.load();
System.out.println("22");
}
System.out.println("33");
}else
{
System.out.println("NULL POST WORLD");
}
 
for(Player p : players)
{
System.out.println(p.getName());
ArenaAPI.resetPlayerState(p);
p.teleport(getPostGameSpawn());
}
}

But obviously I need that method to teleport the players to the other world..

And the other funny thing about this is that if I let that method run, it all runs through (all debug println show) and the error doesnt occur until what I said above ^^

Ignore the debugging println

bump.. still having this issue
