> Testing the shared durable subscription functionality against Qpid Broker-J I
> found that if I attempted to unsubscribe a shared durable subscription from
> client A, while still having an active consumer from client B, then no
> exception was thrown in client A.
> The protocol trace from the client A is as follows:
> {noformat}
> [362461018:0] -> Attach{name='myDurableSub|global', handle=0, role=RECEIVER,
> sndSettleMode=UNSETTLED, rcvSettleMode=FIRST, source=null,
> target=Target{address='null', durable=NONE, expiryPolicy=SESSION_END,
> timeout=0, dynamic=false, dynamicNodeProperties=null, capabilities=null},
> unsettled=null, incompleteUnsettled=false, initialDeliveryCount=null,
> maxMessageSize=null, offeredCapabilities=null, desiredCapabilities=[shared,
> global], properties=null}
> [362461018:0] <- Attach{name='myDurableSub|global', handle=0, role=SENDER,
> sndSettleMode=UNSETTLED, rcvSettleMode=FIRST, source=Source{address='topic',
> durable=CONFIGURATION, expiryPolicy=NEVER, timeout=0, dynamic=false,
> dynamicNodeProperties=null, distributionMode=copy, filter=null,
> defaultOutcome=Modified{deliveryFailed=true, undeliverableHere=null,
> messageAnnotations=null}, outcomes=[amqp:accepted:list, amqp:released:list,
> amqp:rejected:list], capabilities=[global, shared, topic]},
> target=Target{address='null', durable=NONE, expiryPolicy=SESSION_END,
> timeout=0, dynamic=false, dynamicNodeProperties=null, capabilities=null},
> unsettled={}, incompleteUnsettled=false, initialDeliveryCount=0,
> maxMessageSize=null, offeredCapabilities=[SHARED-SUBS],
> desiredCapabilities=null, properties={}}
> [362461018:0] -> Detach{handle=0, closed=true, error=null}
> [362461018:0] <- Detach{handle=0, closed=true,
> error=Error{condition=amqp:resource-locked, description='There are consumers
> on Queue 'qpidsub_/_global__/myDurableSub_/durable'', info=null}}
> [362461018:0] -> Close{error=null}
> [362461018:0] <- Close{error=null}
> {noformat}
> While the broker is sending back a detach with closed=true (which is
> essentially accurate) it is also providing an error. The JMS API docs have
> this to say:
> {quote}
> It is erroneous for a client to delete a durable subscription while there is
> an active (not closed) consumer for the subscription, or while a consumed
> message is part of a pending transaction or has not been acknowledged in the
> session.
> {quote}
> So I presume we should be triggering off the fact that the broker sent detach
> contains an error to throw an appropriate JMSException
