The correct MBean name is:

The jconsole (at least with Java 6) displays the object name of any MBean.

I don't know if it applies to your problem but you could setup a Camel
routing on the broker so that the 10'000 queues are forwarded into a
few, so that each client would only have to listen to 10 or so queues
(like one per broker).

The default JDBCPersistenceAdapter has access to the BrokerService.
The broker service exposes the ManagementContext that contains a
