WebLogic JMS client - reading multiple queues using async and sync API does not commit all messages.

Problem when reading messages from multiple JMS Queues in a single transaction using WebLogic JMS client (wlthin3client.jar) from WebLogic 11g (WebLogic Server

Try to read first one message from queue Q1 and then, if this message satisfy some requirements, read other message (if available at that time) from queue Q2.

Expectation is that after committing the transaction both messages should disappear from Q1 and Q2. In case of rollback - messages should remain in both Q1 and Q2.

Initial approach was to use an asynchronous queue receiver to read from Q1 and then synchronously read from Q2 when it is needed:

void run() throws JMSException, NamingException {
  QueueConnectionFactory cf = (QueueConnectionFactory) ctx.lookup(connectionFactory);

  // create connection and session
  conn = cf.createQueueConnection();
  session = conn.createQueueSession(true, Session.SESSION_TRANSACTED);
  Queue q1 = (Queue) ctx.lookup(queue1);

  // setup async receiver for Q1
  QueueReceiver q1Receiver = session.createReceiver(q1 );


  // ...
  // after messages are processed

public void onMessage(Message q1msg) {
  try {
  QueueReceiver q2receiver = session.createReceiver(queue2);
  // synchronous receive from Q2
  Message q2msg = q2receiver.receiveNoWait();
  } catch (JMSException e) {
  } finally {

Even though when a session.commit() is executed, the message from Q1 remains uncommitted.

It is in receive state until the connection or receiver is closed. Then it seems to be rolled back as it gets delayed state.
