That's because publishing is asynchronous. The channel will have closed<br>
due to the permission error but if you just publish and do nothing else<br>
your app won't notice.<br>
<br>
Ways you could notice:<br>
<br>
* Publish in confirm mode and await a basic.ack<br>
* Publish in mandatory mode and await a basic.return<br>
* Publish in a transaction<br>
<br>
These all have performance costs (in approximately increasing order).<br>
<br>
Cheers, Simon<br>
