----------------------------------------

Robbie,

I believe you put this on hold based on a request from me.
Sorry for not following up with you on this.

Would you like to go ahead and commit this patch now?

Regards,

Rajith

> AMQSession.createDurableSubscriber(topic, name, messageSelector, noLocal) does not unsubscribe
existing durable subscriptions. Whilst it does check for existing durable subscriptions in
use by the client with the same name, it instead simply closes the subscriptions then creates
a new one. As a result of not unsubscribing, the queue backing the subscription is not deleted
before being used by the updated subscription as it should be (and as happens in the 0_8 and
0_10 subclasses when using durable subscriptions without selectors).
