HornetQ - QueueBrowser doesn't find messages in getEnumeration

Question

I need to read the messages added in a Queue, just for visualization, but I never can get the messages.

        Queue queue = (Queue) new InitialContext().lookup("jms/queue/orderDuplicateQueue");

        List<OrderManager> list = new ArrayList<>();
        Connection connection = null;
        Session session = null;

        ConnectionFactory cf =  (ConnectionFactory) new InitialContext().lookup("java:/ConnectionFactory");
        connection = cf.createConnection();
        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        QueueBrowser browser = session.createBrowser(queue);
        @SuppressWarnings("rawtypes")
        Enumeration messageEnum = browser.getEnumeration();

        while (messageEnum.hasMoreElements()) {
            Message nextElement = (Message) messageEnum.nextElement();
            OrderManager order = nextElement.getBody(OrderManager.class);
            order.set_id(nextElement.getJMSMessageID());
            list.add(order);
        }

        browser.close();

        return list;

Note: After some time, I tried to comment the consumer of this Queue, then I can read all the messages. I uncommented the consumer, and can not read anymore.

The consumer configuration:

@MessageDriven(name = "MessageMDBOrderDuplicateQueu", activationConfig = {
  @ActivationConfigProperty(propertyName = "maxSession", propertyValue = "3"),
  @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
  @ActivationConfigProperty(propertyName = "destination", propertyValue = "/jms/queue/orderDuplicateQueue"),
  @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
  @ActivationConfigProperty(propertyName = "clientFailureCheckPeriod", propertyValue = "600000"),
  @ActivationConfigProperty(propertyName = "connectionTTL", propertyValue = "-1") }) 
public class OrderDuplicateMDB implements MessageListener {
