AMQP 1.0 JMS Client hangs on connection.close

I have already created a JIRA ticket for this here
https://issues.apache.org/jira/browse/QPID-5439

However, I wanted to get some attention to this issue since it is a
"blocker" for my current project.

I am trying to figure out what could be wrong but haven't had any luck with
it yet. Maybe someone else has come across this issue already and found
either a work-around or a fix.

Thanks in advance,
-Uli
