Error description

• The following code;
  
      try
      {
        queueSender.send(message);
        queueSession.commit();
        fail("Exception expected");
      }
      catch(JMSException e)
      {
        //e.printStackTrace();
      }
  
      queueSender.close();
      queueSession.close();
  
  sends a message which (correctly) throws an exception when
  committed. The transaction is automatically rolled back but
  when queueSession.close is called,
  the following exception is (incorrectly) thrown...
  
  javax.jms.JMSException: CWSIA0053E: An exception was received
  during the call to the method JmsSessionImpl.close:
  com.ibm.websphere.sib.exception.SIIncorrectCallException:
  CWSIC1022E: An attempt has been made to call a method on a
  transaction object when the transaction has already been
  committed or rolled back..
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users using JMS queues and transactions  *
  ****************************************************************
  * PROBLEM DESCRIPTION: Exception thrown on session close       *
  *                      after rollback.                         *
  ****************************************************************
  * RECOMMENDATION: Apply this fix                               *
  ****************************************************************
  User code which tries to close a session where the transaction
  has already been rolled back will receive a JMSException
  indicating that the transaction has been rolled back.
  

Problem conclusion

• This fix changes the behaviour of the close method so
  that the exception is no longer thrown if the transaction
  has been rolled back.
  

Temporary fix
