Rob Godfrey commented on QPID-792:
----------------------------------
I'm strongly of the opinion that when you create a consumer or a browser you
should get an exception if the queue you are trying to consume from / browse
does not exist - that is certainly the intent of the JMS API I believe. As such
I believe an exception here would be valid (and the fact that historically we
have created queues when creating consumers is an aberration).
Getting the queue out of JNDI doesn't seem an appropriate time to validate as
at that point you don;t necessarily have a connection to validate with.

> While debuggin and issue I noticed the following behaviour in the
> AMQQueueBrowser class.
> 1) When we create a queue browser we do a subscribe immediately
> followed by a cancel. (And then we subscribe again when we enumerate).
> The rationale for doing so it to verify the selector is valid. This is
> very confusing for customers who look at the log and it is not appropriate
> IMHO.
> Currently we use client side selectors, so it is easy validate this. The
> above step is completely unnecessary.
> If we are to use server side selectors the right way to do is
> a)Send a subscribe with the selector
> b)Give message credits only when you call the enumerate method.
