-------------------------------

             Summary: Failover with client ack mode consumer can loose a message auto acked
as a duplicate
                 Key: AMQ-4665
                 URL: https://issues.apache.org/jira/browse/AMQ-4665
             Project: ActiveMQ
          Issue Type: Bug
          Components: JMS client
    Affects Versions: 5.8.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.9.0


with a client ack consumer and failover after receipt but before message.ack can result in
a missed message when the message is redispatched and auto acked as a duplicate.
Failover interrupt should clear dispatched and unconsumed messages so that they can get redelivered.
auto-acking a duplicate seems over eager. think best to poison pill and now that we can include
a cause property it will be possible to differentiate.
