Entity Servershutdown bug

Hey guys.
Just updated my plugin, everything I added is the code below. Now my server keeps crashing after ~ 10 seconds, when I unload my plugin it works. There is a known 1.8 entity bug, so could any1 tell me how to fix this issue?

Code:

this.getServer().getScheduler().runTaskLater(this, new Runnable() {

         @Override
         public void run() {
           Location loc = p.getLocation();
           loc.setX(-160);
           loc.setY(65);
           loc.setZ(62);
           Villager starter_villager_elf = loc.getWorld().spawn(loc,
               Villager.class);

           starter_villager_elf
               .setProfession(Villager.Profession.LIBRARIAN);
           starter_villager_elf.setCustomName("§a§lGaladriel");
           starter_villager_elf.setCustomNameVisible(true);
           starter_villager_elf.setAdult();
           starter_villager_elf.setAgeLock(true);
           starter_villager_elf.addPotionEffect(new PotionEffect(
               PotionEffectType.SLOW, 100000000, 100));

         }
       }, 50L);

Thanks,

Hey bud post the console error/shutdown code?

 

@Koobaczech It is shutdowned by watchdog:

Code:

2015-07-26 21:06:11 [Server Watchdog/FATAL]: A single server tick took 60.00 seconds (should be max 0.05)
2015-07-26 21:06:11 [Server Watchdog/FATAL]: Considering it to be crashed, server will forcibly shutdown.

(Not my report, but the same message. Too lazy to crash my server again p:

Works when I remove my plugin.
Even WORKS when I remove the code I added.
Strange.

 

This might have something to do with it?

Code:

Location loc = p.getLocation();

Maybe the code is called and it doesn't know what player to get? Or something could be wrong here

Code:

Villager starter_villager_elf = loc.getWorld().spawn(loc,
               Villager.class);

Try spawning a villager at a static location just to test if the server goes down when it gets spawned. Sorry i can't be of more help!

 

@Koobaczech np, I used the code before with p.getLocation().
worked fine every time.

I spawned the villager this way at the players location
worked fine every time.

The problem has to do with the Scheduler, I simply know it.

 

Moved to Bukkit Alternates.

 

Then maybe try to do this

Code:

Bukkit.getScheduler().scheduleSyncDelayedTask(this, new Runnable() 

instead of runtasklater? So

Code:

this.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() {
         @Override
         public void run() {
           Location loc = p.getLocation();
           loc.setX(-160);
           loc.setY(65);
           loc.setZ(62);
           Villager starter_villager_elf = loc.getWorld().spawn(loc,
               Villager.class);
           starter_villager_elf
               .setProfession(Villager.Profession.LIBRARIAN);
           starter_villager_elf.setCustomName("§a§lGaladriel");
           starter_villager_elf.setCustomNameVisible(true);
           starter_villager_elf.setAdult();
           starter_villager_elf.setAgeLock(true);
           starter_villager_elf.addPotionEffect(new PotionEffect(
               PotionEffectType.SLOW, 100000000, 100));
         }
       }, 50L);

 

@Koobaczech Will try that one
But now it isnt even working with an older version of the plugin, Bukkit is strange sometimes

 

Yea it gets frustrating sometimes! haha

 

@Koobaczech
Wow. When I use your code, it shutsdown after ~ 1 sec :3
I don't know what the hell I did wrong...

So what happens:
Ticks are behind (for whatever reason)
Watchdog kills Server

 

lmao. paste the whole code you have written and il mess with it

 

@Koobaczech You dont want that code It is terrible, false variable names, etc...
Im learning Java while doing this, but if you want....

So it works for me, i think your bug is somewhere else than in that runtasklater spawn code

 

@Koobaczech Well, which bukkit version are you using?
I belive it is more of a bug... :3

 

1.8

 

@Koobaczech I even switched it.
It is confirmed. Bukkit hates me.

 

Haha awe. Dude I'm sorry. I think your bug/code is happening somewhere else than in that code. It could even be watchdog settings not allowing entities or something strange! A lot of different factors come into play

 

@Koobaczech Yea, the problem is I can spawn it when I use the players location.
Some bugs are so strange..

 

This is why we all need to become super smart and recode bukkit

 

@Koobaczech
The villager is spawning.
Everything is fine.
And then... 1, 2, 3 RANDOM!
The Server crashes.

 

Lol! wtheck. Hey send me your compiled plugin, i want to try and run it

 

here you are
https://mega.co.nz/#!RlcHQIrY!nSZoT9W3F5YYIQLMPnoqe25KbPyeryAhw6KKTZZb76c
but I belive it isnt the code, more the craftbukkit file...
