------------------------------------

             Summary: Qpid Deadlock during JMS connection close when connected to ActiveMQ
                 Key: QPID-5756
                 URL: https://issues.apache.org/jira/browse/QPID-5756
             Project: Qpid
          Issue Type: Bug
          Components: Java Client
    Affects Versions: 0.27
         Environment: Qpid JMS libraries 0.27 SVN revision 1547654 with socket timeout patch
AMQP JMS Client was running on 64-bit Linux with JDK 1.7
AMQP Broker was ActiveMQ 5.8 running on EC2 64-bit Linux

            Reporter: Michael Samson
         Attachments: QPID-5756.patch, QpidProducerTestWithClose.java, activemq.xml

1. While sending JMS messages to ActiveMQ broker, the ActiveMQ server threw an OutOfMemoryException.
2. Our code processed a JMSException and attempted to shut down the Qpid JMS connection and
this processing deadlocked. 
3. I took several thread dumps in succession (waiting several minutes in between) and noticed
that Qpid was deadlocked.  I even killed ActiveMQ and Qpid was still deadlocked.  Below are
the some relevant threads:
