JDBCMessageStore message audit suppresses composite destination and DLQ messages as duplicates
----------------------------------------------------------------------------------------------

                 Key: AMQ-2800
                 URL: https://issues.apache.org/activemq/browse/AMQ-2800
             Project: ActiveMQ
          Issue Type: Bug
          Components: Message Store
    Affects Versions: 5.3.1
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.4.0


With the audit enabled, messages send to composite destinations are suppressed as duplicates
so the will not survive a restart. In addition, persistent DLQ messages are suppressed (depending
on the audit depth).
Disabling the audit on the persistence adapter works around this issue. It is ok to disable
the audit. The audit is needed to close a small window where duplicate message sends can occur
with the non transactional use of the failover: transport. It can happen if a send is in progress
when a failover reconnection occurs back o the same broker (as if there was a temp network
partition) and the send reply is not received. A non transactional client will resend the
message which needs to be suppressed by the audit. Disabling the audit leaves the possibility
of having a duplicate message in the database that will not be dispatched.
