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

             Summary: Joram test TopicSessionTest#testDurableSubscriber hangs 
against Java Broker when invoked a second time
                 Key: QPID-6738
                 URL: https://issues.apache.org/jira/browse/QPID-6738
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall


If I run 
{{org.objectweb.jtests.jms.conform.session.TopicSessionTest#testDurableSubscriber}}
 twice against the Java Broker using the qpid-jms-client (0.5.0), the second 
invocation always hangs with a NPE reported client side.

Execute the following command twice to reproduce, having first started a Java 
Broker in default configuration with HTTP basic auth enabled.

{{mvn -f joramtests/pom.xml integration-test  -Djoramtests=qpid-jms-client
