    Description

      When consumer is created on started connection and connection is stopped after that, the consumer can receive messages on stopped connection. The following code demonstrates the issue (It create a consumer on started connection, stops the connection and publishes the messages. Than, it opens a new connection to consume, but, no message is received because they are got prefetched by the consumer on stopped connection)

      try (Connection connection = createConnection())
      {
          connection.start();
          Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
          Queue queue = session.createQueue("test");
      
          MessageConsumer consumer1 = session.createConsumer(queue);
          connection.stop();
      
          MessageProducer producer = session.createProducer(queue);
      
          for (int i = 0; i < 4; i++)
          {
              producer.send(session.createTextMessage("msg-" + i));
          }
      
          System.out.println(".... Messages are sent... Start consuming.....");
      
      
          try(Connection connection2 = createConnection())
          {
              connection2.start();
              Session session2 = connection2.createSession(false, Session.AUTO_ACKNOWLEDGE);
              MessageConsumer consumer2 = session2.createConsumer(queue);
      
              int receivedMessageCounter = 0;
              for (int i = 0; i < 4; i++)
              {
                  Message m = consumer2.receive(2000);
                  if (m != null)
                  {
                      receivedMessageCounter++;
                      System.out.println("Received message :" + ((TextMessage) m).getText());
                  }
              }
              System.out.println("Total Received : " + receivedMessageCounter);
          }
      }
