> QueueBrowser hangs on reaching an end of the queues. The following code
> reproduced the issue:
> {code:java}
> Queue queue = QueueImpl.createQueue("testQueue");
> ConnectionFactory factory = new ConnectionFactoryImpl("localhost", 5672,
> "admin", "admin");
> Connection producerConnection = factory.createConnection();
> Session producerSession = producerConnection.createSession(false,
> Session.AUTO_ACKNOWLEDGE);
> MessageProducer producer = producerSession.createProducer(queue);
> producer.send(producerSession.createTextMessage("message 1"));
> producer.send(producerSession.createTextMessage("message 2"));
> producerConnection.close();
> Connection browserConnection = factory.createConnection();
> Session browserSession = browserConnection.createSession(false,
> Session.AUTO_ACKNOWLEDGE);
> QueueBrowser browser = browserSession.createBrowser(queue);
> @SuppressWarnings("rawtypes")
> Enumeration enumeration = browser.getEnumeration();
> while (enumeration.hasMoreElements()) // <--- hangs here
> {
> TextMessage msg = (TextMessage) enumeration.nextElement();
> System.out.println("Browser received:" + msg.getText());
> }
> browserConnection.close();
> {code}
