If you are publishing with the 'immediate' flag asserted, to an exchange 
that in turn routes to a single queue without consumers, and you have a 
returnlistener set up on the same channel then the handleBasicReturn 
method in the returnListener should get called.

Can you supply a minimal runnable piece of code that exhibits the 
problem you describe?
