Description

When connection is lost and failover is started the Qpid Client should block on invocation of JMS operations which require sending or receiving data over the network.
With current implementation the performing of certain operations during failover can lead to unexpected behaviour.
For example, closing QueueBrowsers during failover has been observed to cause issues because it is possible to send the old subscription destination in a cancel command to the new broker as the close and failover are allowed to progress concurrently. As result of it the broker might close the session with a NOT_FOUND execution exception because failover has not finished queue re-creation on a new broker
