                 URL: https://issues.apache.org/activemq/browse/AMQ-2048
             Project: ActiveMQ
          Issue Type: Test
          Components: Broker
    Affects Versions: 5.1.0
         Environment: Microsoft Windows Server 2003 - Standard x64 Edition - Service Pack

Virtual Topic: VirtualTopic.AckTest
Physical Queue of Virtual Topic: Consumer.TestQueueAcknowledgement.VirtualTopic.AckTest

Consumer is connected to Openwire TCP connector and I am posting messages directly to the
virtual topic.

Even if message.acknowledge() is called, messages are read but not removed from queue.  "Messages
Received" count remains at zero.  Is this the expected behavior while using Virtual Topics?

Test Consumer:

import java.util.Properties;

import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.QueueConnection;
import javax.jms.QueueSession;
import javax.jms.TextMessage;
import javax.naming.InitialContext;


public class TestQueueAcknowledgement {

	private QueueConnection conn;
	private QueueSession session;
	
	public void listen() {
		try {
			Properties props = new Properties();
			props.put("java.naming.factory.initial", 
					"org.apache.activemq.jndi.ActiveMQInitialContextFactory");
			props.put("java.naming.provider.url", 
					"tcp://localhost:61616");
			props.put("queue.queueName", 
					"Consumer.TestQueueAcknowledgement.VirtualTopic.AckTest");
			
			javax.naming.Context ctx = new InitialContext(props);
			javax.jms.QueueConnectionFactory factory 
				= (javax.jms.QueueConnectionFactory) 
				ctx.lookup("ConnectionFactory");
			conn = factory.createQueueConnection();
			final javax.jms.Queue queue 
				= (javax.jms.Queue) ctx.lookup("queueName");
			session = conn.createQueueSession(false, 
					QueueSession.AUTO_ACKNOWLEDGE);
			javax.jms.QueueReceiver receiver = session.createReceiver(queue);
			
			receiver.setMessageListener(new MessageListener() {
				public void onMessage(Message message) {
					try {
			            if (message instanceof TextMessage) {
			                TextMessage txtMsg = (TextMessage) message;
		                    String msg = txtMsg.getText();
		                    System.out.println(msg);
			            }
						message.acknowledge();
					} catch (Exception e) {
						e.printStackTrace();
					}
				}
			});
			conn.start();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	protected void finalize() throws Throwable {
		if (session != null) {
			session.close();
		}
	}
	
	public static void main(String[] args) {
		TestQueueAcknowledgement ack = new TestQueueAcknowledgement();
		ack.listen();
	}
}
