Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.2.0
Environment: solaris 10
Reporter: ying
Priority: Blocker
Fix For: 5.3.0
1. producer of VirtualTopic.testTopic publish message to brokerA
2. consumer 1 on brokerB with "Consumer.A.VirtualTopic.testTopic
consumer 2 on brokerB with "Consumer.A2.VirtualTopic.testTopic
3. brokerA and brokerB are bridged.

ERROR MasterBroker - Slave Failed
javax.jms.JMSException: Slave broker out of sync with master - Message:
ID:yhe-1337-1236273055924-0:16:1:1:738 on queue does not exist among pending(0)
for subscription: ID:yhe-3603-1236271682179-0:13:1:1
Reason:
In TransactionBroker.java there is a ActiveMQMessageAudit and it will be
configured if the broker is a slave. ActiveMQMessageAudit is using the
messageId alone to check whether the message is a duplicate. The message for
consumer2 will be ignored as duplicate and not saved to the message store
because consumer1's same message arrives early.
