> 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
