> Key: QPID-7060
> URL: https://issues.apache.org/jira/browse/QPID-7060
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.0
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Priority: Minor
> Fix For: qpid-java-6.0.1, qpid-java-6.1

> As highlighted by the following test failure:
> https://builds.apache.org/view/M-R/view/Qpid/job/Qpid-Java-Java-Test-IBMJDK1.7/1440/testReport/org.apache.qpid.test.unit.xa/FaultTest/testForget/
> On the 0-10 path, a closed disassociates the connection from the virtual host _before_ closing the session(s) and causing the connection model object to closed. This means that if an close initiated by the client occurs just before a Broker shutdown, a rice is possible. The VHN will shutdown the VH executor as soon as the last connection is disassociated, so the following stack trace is possible:
