activemq中的topic队列在删除队列后消费者依然能够接收到请求

我在jmeter中对一个http接口进行了一百次请求

接口如下:

@GetMapping("send")
    public void send(String msg) {
        // 指定消息发送的目的地及内容
        System.out.println(new Date().toString());
        queueMessageService.setTopic("topic",msg);
    }

调用的Bean

@Component
public class QueueMessageService {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    public void setQueue(String queue,String msg){
        jmsMessagingTemplate.convertAndSend(new ActiveMQQueue(queue),msg);
    }
    public void setTopic(String topic,String msg) {
        jmsMessagingTemplate.convertAndSend(new ActiveMQTopic(topic),msg);
    }
}

我使用了两个消费者用于接收请求

  @JmsListener(destination = "topic")
    public void receiveMessage(String message) throws InterruptedException {
        Thread.sleep(4000);
        System.out.println(hfnsTermService.getCount());
        System.out.println(new Date().toString()+"topic接收:"+message);
    }
    @JmsListener(destination = "topic")
    public void readResponse(String message) throws InterruptedException {
        Thread.sleep(1000);
        for(HfnsTerm hfnsTerm:hfnsTermService.getHfnsTerm()){
            System.out.println(hfnsTerm.getId());
        }
        System.out.println(new Date().toString()+"topic1接收:"+message);
    }

当我在请求还没完全接收完时在activemq控制台把topic队列进行了删除操作

此时activemq中是没有topic队列的，但是我依然能够接收到topic队列中的消息

请问这是为什么？
