----------------------------------------------------------------
Another thing to note. You don't have to switch on VirtualTopics for certain
addresses. The virtual topic feature maps to just creation of queues in
Artemis. The architecture in Artemis is different to ActiveMQ. We actually
don't have topics, we deal only with addresses and queues. A topic
subscription in Artemis is just a queue bound to an address with multicast
routing type, which essentially just means that the queue receives a copy of
each message sent it's address.
Normally the protocol managers take care of creating subscription queues on
behalf of the clients. All that is happening when you use "FQQN" or "Aliasing
in this case" is that you are bypassing the protocol manager and directly
creating your own subscription queue.
