ActiveMQ should support local transaction even in JTA mode



    • Bug
    • Status: Open
    • Major
    • Resolution: Unresolved
    • 5.16.0, 5.16.1
    • None
    • XA
    • None


      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 

      javax.jms.JMSException: Session's XAResource has not been enlisted in a distributed transaction.
       at org.apache.activemq.ActiveMQXASession.doStartTransaction(ActiveMQXASession.java:101) 

      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 (transacted) 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.
