Duplicate delivery acks on failover with transacted delivery - Async error on broker - TX has
not started error on ack
----------------------------------------------------------------------------------------------------------------------

                 Key: AMQ-2004
                 URL: https://issues.apache.org/activemq/browse/AMQ-2004
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.2.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.3.0


On failover transport resume, outstanding acks are delivered async. Regular consumption also
delivers acks which can result in out of order delivery of outstanding delivery acks. the
async delivery can occur after the regular delivery.
org.apache.activemq.transport.failover.AMQ1925Test.testAMQ1925_TXBegin modified to fail on
a connection exception demonstrates this behaviour.
Solution seems to be  to only deliver outstanding standard acks during deliverAcks.
