Gary Tully resolved AMQ-2121.
-----------------------------
Resolution: Fixed
brokerService was an inappropriate shared lock, using the VMUrl is less
contentious, no real need for a seperate lock object.
rev: 744975
> Occasional Deadlock in DuplexNetworkMBeanTest - contention on brokerService
> with NetworkConnector
