When a JMS destination is created, we expose it in the management model (in jms-queue)
However, creating a JMS destination may also result in the creation of core-queues resources (1 for JMS queues, 1 per subscribers for JMS topics). This core queues are not exposed in the management model. Only those configured in config files or CLI are present.
(However we make sure that we add core addresses (1 for each JMS destination) at runtime to the management model)
This means that AS7 messaging subsystem is not a "correct" reflection of the HornetQ runtime. I can't make my mind whether it is a problem. Afaict, most operations on these underlying queues can be also done at the JMS destination level through their management operations.
