I've got several AMQ 4.0.1 brokers in an environment, and I'm introducing one
AMQ 4.1 broker. The AMQ 4.0.1 brokers are getting this exception while
trying to connect to the AMQ 4.1 broker:
Failed to unregister mbean: org.

I assume we should be able to do a rollout for AMQ 4.1, as opposed to me
upgrading all 50 of my brokers at one time, right?
