i get the following errormessage out of the blue sky:
12.11.2008 01:13:21 com.captiveimagination.jgn.DefaultUncaughtExceptionHandler uncaughtException
SCHWERWIEGEND: Uncaught exception: Terminating Thread.

I think the error comes from my SynchronizationManager for my vehilce...
how could i find out the reason for the error, because from the errormessage i can only guess where the null pointer could be.
when i switch client and server (execute the same code on a different computer in my network) i get:

It looks like you're sending some object that JGN is not able to properly serialize / deserialize and causes it to fail. What does your Message object look like?
Just an observation from looking at the stack, wouldnt you be better pushing read bytes to a queue that is processed by other threads, that way you maximise the network socket reading ??
I do both…I separate the functionality out because there's a lot of logic about how messages get where they belong, so in the end I fill up a ByteBuffer with as many messages as it will hold and continue to push that to the NIO connection until it's empty.
