Thanks for your replies!

When do you need the subject, on the producer side or with message
> listeners?


I have been assuming on the message listener side.  I will be listening to
multiple topics from different sources.

I'll look into that too

I think there is a deeper than a threading issue here. The subject needs to

I started down that path by using camel-shiro.  It ended up not being what
I was looking for as that was message based authentication, and I was
looking for topic based.  At this point I am assuming a message sent by a
broker (which checks the authc and authz ) is valid.

Lots of assumptions at this point.  I follow up with the ActiveMQ list and
follow up here with the result for those interested.

Thanks again!
