Actually I were able to reproduce it every time, I started the app.
Nothing much going on, but as soon I as recieved a message a create
a session/producer from the replyto dest, then it will just hang there...
maybe the other end (ie. the broker) is somehow faulty and dont return
a response so createsession just hangs...

we restarted the broker and now it works... (until next time)...

should it throw an exception right away or after some time ?
