[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1440) JTA-prepared message delivered to other consumer.

    [ https://jira.jboss.org/jira/browse/JBMESSAGING-1440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12437769#action_12437769 ] 

Tim Fox commented on JBMESSAGING-1440:
--------------------------------------

>> I believe commit() should go "after" since my code may not be the one who controls the global transaction

In a managed environment, the JCA layer should ensure that the session doesn't actually get closed until later.

> Today I re-tested my two server scenarios and committing "before" or "after" did not make any difference: I got the same massage delivered and committed twice. 

Ok, if you can provide a new test case demonstrating this, we can investigate further.

> You are right, if I do not use XA, the issue is not applicable - close always rollback. 

I was referring to JmsXA, not XA, per se. JmsXA is the JCA JMS resource adapter, not part of JBM.

>             Project: JBoss Messaging
>          Issue Type: Bug
>         Environment: JBoss 4.2.2 + JBM 1.4.0.SP3. Windows XP.
>            Reporter: szhigunov
>            Assignee: Tim Fox
>             Fix For: 1.4.0.SP3.CP05, 1.4.2.GA

> The problem is that when fully prepared tx1 fails in the commit phase, JBM delivers the message second time in tx2, while tx1 is still in progress. Eventually recovery commits tx1, so the message gets delivered and committed twice.
> The attached test (myxatest.zip) is a clean JBoss 4.2.2 + JBM 1.4.0 SP3 with my test MBean: jboss-4.2.2.GA\server\messaging\lib\myxatest.jar (code and source) + jboss-4.2.2.GA\server\messaging\deploy\myxatest-service.xml.
> Steps to reproduce the problem:
> 1.	Start the server.
> 2.	Go to JMX console + myxatest + service=Test. Invoke send.
> 3.	Go to JMX console + jboss.messaging.destination + name=A.service=Queue. Verify MessageCount=1.
> 4.	Go to JMX console + myxatest + service=Test. Invoke receive. That will start XA transaction; enlist DummyXAResource; get JMS connection from JCA and receive message. DummyXAResource sleeps 60 sec inside the commit call.
> 5.	Verify that DummyXAResource prints "DummyXAResource commit start sleeping for 60 sec" message.
> 6.	Go to JMX console + jboss.jca + name=JmsXA,service=ManagedConnectionPool and invoke stop(). Check that DummyXAResource finished commit and printed "DummyXAResource commit end" message. JBM commit fails.
> 7.	Now we have fully prepared JBM transaction in progress. You can see one record in JBM_TX.
> 8.	Go to JMX console + jboss.jca + name=JmsXA,service=ManagedConnectionPool and invoke start().
> 9.	Go to JMX console + myxatest + service=Test. Invoke receive again. Same message delivered again. And this is wrong. Wait for a minute and let transaction finish successfully.
> 10.	Got to JBM_TX and verify that transaction is still there (nobody recovered it!).
> 11.	Stop server, enable JBM recovery, start server. In couple minutes the original transaction is found and committed (second time). JBM_TX is empty.
