KeyPacket isn't an existing packet on any L2 chronicle (at least up to Grand Crusade, and since you use net.sf.l2j you're probably IL or near), so I suppose it's a custom packet used by strix patlform and it fails somehow.

 

Technically speaking, it can be explained as your "buffer" from where you try to parse your writeB doesn't exist. It's not empty, it simply doesn't exist. Can be because you flushed the _buf meanwhile (_buf = null while accessing it and not locking it), can be because you tried to access to it while it wasn't initialized.

 

Better ask to Strix guys why their custom stuff doesn't work :].
