That's because publishing is asynchronous. The channel will have closed 
due to the permission error but if you just publish and do nothing else 
your app won't notice.

Ways you could notice:

* Publish in confirm mode and await a basic.ack
* Publish in mandatory mode and await a basic.return
* Publish in a transaction

These all have performance costs (in approximately increasing order).

Cheers, Simon
