Keith Wall created QPID-7060:
--------------------------------
Summary: [Java Broker] [0-10] Connection close disassociates
virtualhost before closing sessions and connection model object
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
Fix For: 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:

This error is possible only when shutting down a Broker. There is negligible
end-user impact.
