> According to the JMS API documentation, the createQueue method should not create a physical queue in the broker.
> Currently if just a queue name is passed, then the current implementation will create a queue if the destination is used by a consumer or producer.
> Before this change was made in rev 964984, an AMQQueue object was created with durable true and a queue was created in the broker when the destination object was used by a consumer.
> Therefore current behaviour is neither spec complaint nor backwards compatible.
> Suggested improvement would be to just create a destination object with "create" set to "never". When a producer or consumer is created using this destination it will try to resolve if the queue is present, and if not will throw an exception.
> Therefore the default behaviour would be spec compliant.
> If a user needs to override this behaviour they could easily do so by specifying the correct create option (i.e one of receiver/sender/always).
> A user could also use any valid addressing string to create a more customized destination as well.
