Subject [jira] [Commented] (AMQ-4634) Losing messages when there is a XA trx timeout
Date Wed, 17 Jul 2013 21:17:47 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4634?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13711637#comment-13711637

Gary Tully commented on AMQ-4634:
---------------------------------

@Gaston I think your issue is fixed by http://svn.apache.org/r1504279
the only caveat is that my use case does not need a call to another ejb. The scenario was
an MDB spending longer than the TM timeout in onMessage so that the CMT had aborted on its
return from onMessage. That was enough to loose a message through an auto ack in a local transaction.
All in error.

Can you try out tonights snapshot to verify?
many thanks :-)

> ActiveMQ does a trx commit when there is a transaction timeout (EJBTransactionRolledbackException).
In this way we are losing messages when there is any timeout.
> We have seen that the activemq connections are enlist in XA.
> The attribute transactionContext from ActiveMQSession class has the global transaction
reference (xid) before calling the MDB (messageListener.onMessage(message)).
> When the timeout is reached and the RuntimeException is throwned, the transactionContext
losed the xid reference.
> Later, when ActiveMQSession call the method transactionContext.isInXATransaction() the
result is false because there is no xid reference.
> This situation only happened when the MDB calls other EJB (Stateless) with CMT - TransactionAttributeType.REQUIRES_NEW,
and the exception is throwed inside the Stateless.
> I've tried to reproduce this without calling the stateless ejb but it works well.
> The ActiveMQSession class should retain the original transactionContext.
