      Scenario

      • There is one EAP configured to use JDBC persistence storage.
      • Producer sends 300 messages to InQueue.
      • After that MDB is deployed. It sends messages from InQueue to OutQueue.
      • When half of the messages occurs in the OutQueue, network between EAP and database is failed.
      • Network is down for 16 minutes to cause closing of JDBC connection.
      • Then network is restored and EAP is restarted.
      • After the restart MDB continues in resending of messages from InQueue to OutQueue.
      • Test waits until all prepared transactions are resolved.
      • Receiver receives all messages from OutQueue.

      Expectation: Receiver receives all messages sent by producer.
      Reality: Receiver doesn't receive all messages sent by producer. Some of them are lost.

      Customer impact: If network between EAP and database fails, some messages may be lost.

      When EAP is started after the network was restored, I can see log messages [1] in server.log. These messages corresponds to lost messages.

      When I tracked the XA transactions of lost messages, last information I found was that transactions were successfully rollbacked.
