> I observed a deadlock when running some tests against the Java broker using the new JMS client, apparently occurring when a flow arrived at the broker at the same time a QueueRunner was notifying a consumer that the queue was empty. 
> This further meant that the broker could not be shutdown with a CTRL-C since the shutdown hook waited for one of the locks involved.
> Stack output to be attached.
