Client kick "Exception in world tick"

Hello, I'm developing a plugin called HealthBar, but since I added teams and player bars, some times client crashes with "Exception in world tick". This is the log: http://pastebin.com/zDEyvBwQ
These are the classes of my plugin:
Main: http://pastebin.com/yrrEqEsa
Health lose and regain listener: http://pastebin.com/1ikgjPyq
Death listener (to fix death messages like "player was killed by *healthbar*"): http://pastebin.com/SK1fADyU

The weird thing is that only happens sometimes, and I cannot see any error on console. Maybe a minecraft bug with Teams? Sorry for my english, +1 for the fix

Anyone?

filoghost If you are using scoreboards, you cannot send the scoreboard to the player twice, or the client will crash.

 

I'm not using packets, I'm only using teams, and if I set a team for a player twice, doesn't crash...

 

filoghost But you create the scoreboard twice. That will still crash the players. One way around this is to kick all online players on reload so they dont crash.

 

I think not, read my code...

 

filoghost Just to clarify, is it kicking or crashing the player? Also, can you provide any more info on when it happens?

 

Crashing the player, can't reproduce it...if I could, I would have identified the source of crash...

Bunch of crashes that I believe to be your plugin

I believe some of those have vanilla crashes, some have modded crashes
(The mods I use are Optifine, Reis Minimap, and Too Many Items)
I fixed the issue by installing the version before the one with player HP bars, this also seems to affect people randomly, and it goes away randomly as well

BTW, what is going on with it? Says it's under moderation

 

I changed the name and they told me to change it (no additional informations in the name), now it's ok. Have you tried disabling player bars?

Also, when scoreboard API will come out, will solve this bug?

I just posted that so you could have some logs to try to figure out the error

Also I never found a config for your plugin so I just downgraded to the version without player bars, and it works fine.

 

The config folder should appear on your plugins folder

 

I don't remember seeing it, unless I am going crazy.

 

Are you using v1.2?

 

Bump, still happens wih Scoreboard API that should be safe! Please help me...
