CMDHELPER-2740 - Reported by obviousAce

I use CommandHelper v1565-b841bda and Craftbukkit #2805.
When I start my minecraft server (6GB RAM, Linux) it stops after a while with an error.
Errorcode:
2013-07-04 15:06:13 [SEVERE] Exception in thread "Thread-5"
2013-07-04 15:06:24 [SEVERE] Exception in thread "Abstraction Enum Verification Thread"

Earlier times there were this error:

SORRY! I mean CommandHelper! Not CommandBook.
