------------------------------------
Summary: ActiveMQ should support local transaction even in JTA mode
Key: AMQ-8187
URL: https://issues.apache.org/jira/browse/AMQ-8187
Project: ActiveMQ
Issue Type: Bug
Components: XA
Affects Versions: 5.16.1, 5.16.0
Reporter: Andreas Benneke
When running a JTA environment it comes quite handy to not always having to
blow up a full JTA transaction
if you already know in advance, that a particular interaction does not require
synchronization
with other resources or interactions.
Until 5.15 ActiveMQ did support this, but the last changes in
https://issues.apache.org/jira/browse/AMQ-2659 broke this.
When you now try to interact with ActiveMQ in such a local transaction you get
{code:java}
javax.jms.JMSException: Session's XAResource has not been enlisted in a
distributed transaction.
at
org.apache.activemq.ActiveMQXASession.doStartTransaction(ActiveMQXASession.java:101)
{code}
This is perfectly correct when one want to enforce JTA transactions, but
exactly not wanted for local transactions.
I am not sure, where the problem here is. Some thoughts:
* Until 5.15 the {{ActiveMQXASession}} supported this by itself, but as of
AMQ-2659 it does no longer.
* With AMQ-2659 one could think that the intention of the change was to make
{{ActiveMQXASession}} no longer work outside JTA transactions.
* I am however not sure if the consequence was intended, that is now no longer
working in local transactions as well.
* The {{ActiveMQXASession}} is created by
{{ActiveMQXAConnection.createSession}}, however the first parameter
"transacted" is effectively ignored and a {{ActiveMQXASession}} is returned
even if transacted is false.
* {{createSession(false, ...)}} is exactly what the transaction managers do to
start a session in a local transaction (e. g. see
{{DualSessionWrapper.createNonXASession}} in Bitronix)
* Or are the transaction managers doing something wrong here? If, how should
sessions on such local transactions be initiated?
Please find a stripped down test case here
https://github.com/abenneke/sandbox/tree/master/activemq-local-transactions.
It has tests using Bitronix and Atomikos to reproduce the given cases.
