JMS。在 WildFly 12 中向 ActiveMQ 中的主题发送简单的主题消息失败

Question

我想将一个简单的主题发布到主题队列。因此我在 WildFly 12 中使用 ActivMQ-Extension（在子系统下）。但我收到以下错误：

CompletionListener/SendAcknowledgementHandler used with confirmationWindowSize=-1. Enable confirmationWindowSize to receive acks from server!

这是什么意思？ 我使用以下代码：

@RequestScoped
public class Sender {

    @Resource(lookup = "java:jboss/exported/jms/RemoteConnectionFactory")
    private ConnectionFactory connectionFactory;

    @Resource(lookup = "java:jboss/jms/queue/bookstoreqeue")
    private Queue queue;

    @Resource(lookup = "java:jboss/jms/messagetopic")
    private Topic topic;


    public void send() throws JMSException {
        Connection connection = connectionFactory.createConnection("admin", "admin");

        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        MessageProducer messageProducer = session.createProducer(topic);

        TextMessage message = session.createTextMessage("message");


        MessageConsumer consumer = session.createConsumer(topic);
        consumer.setMessageListener(msg -> System.out.println("Received!"));


        while (true) {

            try {
                TimeUnit.SECONDS.sleep(5);
                messageProducer.send(message, new CompletionListener() {
                    @Override
                    public void onCompletion(Message message) {
                        System.out.println("complete!");
                    }

                    @Override
                    public void onException(Message message, Exception exception) {
                        System.out.println(exception);
                    }
                });
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

我知道我的 MessageProducer 正在向 TopicQueue 发送主题并且有一个订阅者：

这可能是什么问题？ 顺便说一句，队列和主题都出现相同的错误...
