exception during cleanup

[jdv145]

First some preliminary results of my usage of netty. I'm using it for a
server to host a boardgave made with flash. It's working way better then
expected and the only problems i have are pretty much only with flash. From
a developer's perspective java is way way better then flash. This also means
netty is working pretty much flawlessly. I will give a  more elaborate
report (with some problems i faced which might be handy for the noobs), but
only after the game goes live (for now the game has pretty much only run in
a test environment with 10 ppl at most and artificial load generation). You
did a real good job. A lot of people which will be playing my game are
thankful for it ;). Im glad i made the jump from mina to netty, mina is
okay.. but i like netty better  :).

Anyway, i just got an exception. It doesn't happpen often and I cant seem to
reproduce it (but i didn't really tried it either). Did i something wrong or
is there a bug in netty? If you need a stackdump you have to help me a
little cause i haven't made one ever :P.
