> Messages can get poisonAcked in error as duplicate deliveries when a local
> transaction rollback during/after a failover (auto reconnect) event.
> The interaction between rollback and failover redelivery has a bunch of
> timing issues and did create duplicates in-error that resulted in over eager
> suppression.
> There are a bunch of related tests that validate expected behaviour, the
> related fixes needed to be revisited to better manage the delivered and
> unconsumed messages in the context of a local transaction and to avoid the
> real duplication of delivery in the client.
> There is an additional new test that demonstrates the additional dlq or
> duplicates behaviour.
> a nice cross section from the unit test suite is:
> mvn clean install
> -Dtest=CloseRollbackRedeliveryQueueTest,AMQ2149Test,JMSQueueRedeliverTest,RedeliveryPolicyTest,FailoverTransactionTest,FailoverDurableSubTransactionTest,JMSConsumerTest,JmsSessionRecoverTest,AMQ2751Test
