Ok....But when I modify the program AsynchTopicExample.java that resides
in the swiftmq_2_1_2\samples\sun_examples directory by commenting out
the last line...
topicSession = topicConnection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
topicSubscriber = topicSession.createSubscriber(topic);
topicListener = new TextListener();
topicSubscriber.setMessageListener(topicListener);
topicConnection.start();
//exitResult = SampleUtilities.wait_for_quit();
...the publisher-thread still publishes its messages but the
subscriber-thread never recieves them? (because its finished?)
Why is this?
(The wait_for_quit() contains a while loop that reads from the keyboard
and waits for the q-key beeing pressed.)

The only reason why we put sometimes a wait after subscriber creation is
to guarantee that the subscriber in a multi-threaded app is in place
before a publisher sends messages. That's all.
