Keith Wall created QPID-8040:
--------------------------------
Summary: [Broker-J] Uncaught
java.nio.channels.CancelledKeyException seen during Broker shutdown
Key: QPID-8040
URL: https://issues.apache.org/jira/browse/QPID-8040
Project: Qpid
Issue Type: Bug
Components: Broker-J
Affects Versions: qpid-java-broker-7.1.0
Reporter: Keith Wall
Priority: Minor
The following exception was trapped by the UncaughtExceptionHandler during a
shutdown of the Broker. The would have caused a abnormal termination. I
expect it could also happen during a HA virtualhost mastership change too.
This code hasn't changed, so I think the problem is probably longstanding.
