---------------------------------------
Hi [~svoss] thanks for your issue.
>From what I see this looks totally valid for me and should terminate.
I remember that we had an issue reported about the WorkerGroup staying open
some weeks ago but this one was fixed by me.
Did you try the 0.7.0 Release or a current snapshot?
If its in a current snapshot we would need to check the complete Netty cleanup.
Probably I missed something although I would _think_ its fine atm.
