> Using spring in a standalone framework to connect to C++ broker version M4.  Spring configured
to use the CachingConnectionFactory.  When the broker is killed and restarted the java client
deadlocks more than 50% of the time in closing the connection and sessions.  I originally
ran into this issue against the M4 version of the client.  I updated to 0.6 and still encountered
the issue.  The deadlock from jstack is listed below.  The pertinent info from our spring
configuration:
