> JMX statistics on destinations creates a race condition in the 
> MBeanBridgeDestination's onInboundMessage, onOutboundMessage, and the 
> purgeInactiveDestinationView task.  If the task fires and removes the 
> objectName while the onInboundMessage or onOutboundMessage fires, it will 
> spit out warnings of it already being created if multiple threads are 
> running.  The fix is to properly synchronize in the 
> purgeInactiveDestinationView and also be sure it cleans up itself in the 
> destinationObjectNameMap.
> Patch is attached as is a git pull request (for whatever is easier)
