@Test(timeout = 60000)
public void testZeroPrefetchWithTwoConsumers() throws Exception {
    JmsConnection connection = (JmsConnection) createConnection();
    ((JmsDefaultPrefetchPolicy) connection.getPrefetchPolicy()).setAll(0);

    javax.jms.Queue queue = session.createQueue(getQueueName());
    MessageProducer producer = session.createProducer(queue);
    producer.send(session.createTextMessage("Msg1"));
    producer.send(session.createTextMessage("Msg2"));
    // now lets receive it
    MessageConsumer consumer1 = session.createConsumer(queue);
