Resolved java.io.IOException

A plugin developer has created a plugin for me. It is a SuperCraftBros Brawl plugin. But there is an error. In the Bukkit console nothing is posted (with debugg function). After the countdown, no one can write in the chat any more. And after 15 seconds all be kicked with the error message:

Code (text):

21:58:05 [INFO] falkseidl lost connection: disconnect.endOfStream

.
I have removed all plugins except LilyPad-Bukkit Connect portal and portal-Command. Then it also does not work. If I then remove LilyPad plugins, and connect to the local server, everything works. I also have LilyPad and Bukkit updated several times. So these are the newest Plugin and Server versions. But it is not because of Bukkit, because without LilyPad everything works.
I get this error in the LilyPad Console:

Perhaps the LilyPad Developers can say what the error is, and fix it or give a tip. Sorry for my bad english, iam german.

I installed the latest build. Now everything works.
