JMX Shutdown plugin throws InstanceNotFoundException during broker shutdown
---------------------------------------------------------------------------
Key: QPID-2927
URL: https://issues.apache.org/jira/browse/QPID-2927
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.7
Reporter: Robbie Gemmell
Fix For: 0.7
If the broker is stopped cleanly it emits an InstanceNotFoundException on the
terminal when stopping the JMX Shutdown plugin bundle. This is because the when
the ApplicationRegistry shutdown hook is run, the JMXManagedObjectRegistry
unregisters all MBeans in the 'org.apache.qpid' domain whilst closing,
presumably before Felix is shut down and thus causing the Shutdown plugin to
fail when trying to unregister the shutdown MBean again explicitly.
This can be handled by simply catching the INFE in the Activator, such that the
MBean is unregistered if the bundle were to be stopped before the broker, but
no exception is thrown in the reverse case.
ERROR: Error stopping bundle. (javax.management.InstanceNotFoundException:
org.apache.qpid:type=ShutdownMBean)
