Alex Rudyy updated QPID-3521:
-----------------------------
Description:
failover process for the 0-8 client does not clear the pre-dispatch queue, only
the consumer receive queue.
This is currently masked by an issue with the rollbackMark. The changes made in
QPID-3546 to fix the 0-10 client path need to be applied to the 0-8/9/9-1
client path when this issue is resolved.
We need to clear the pre-dispatch queue on failover. Additionally, we need to
acquire dispatcher and messageDelivery locks in failover thread in order to
prevent the dispatcher from dispatching pre-fetched messages whilst failover is
in progress. If we are not holding the locks, the dispatcher could continue
dispatching prefetched messages into MessageListener which would result in
unnecessary JMSExceptions on acknowledge/rollback/commit/recover.
