### Before Creating the Bug Report - [x] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq/discussions). - [x] I have searched the [GitHub Issues](https://github.com/apache/rocketmq/issues) and [GitHub Discussions](https://github.com/apache/rocketmq/discussions) of this repository and believe that this is not a duplicate. - [x] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ. ### Runtime platform environment any ### RocketMQ version 5.3.2 ### JDK Version jdk8 ### Describe the Bug when shutdown AsyncTraceDispatcher, traceExecutor is not shutdown gracefully. if shutdown producer very quick before send any trace message, after AsyncTraceDispatcher shutdown, AsyncDataSendTask will still execute, and topicPublishInfo of trace topic is null , but traceProducer is shutdown already, updateTopicRouteInfoFromNameServer will fail, then send trace message will fail. so traceExecutor should shutdown gracefully to avoid this scene. ` // AsyncTraceDispatcher @Override public void shutdown() { flush(); this.traceExecutor.shutdown(); if (isStarted.get()) { traceProducer.shutdown(); } this.removeShutdownHook(); stopped = true; } ` my test code: ` public static void main(String[] args) throws MQClientException, InterruptedException, MQBrokerException, RemotingException { DefaultMQProducer producer = new DefaultMQProducer(PRODUCER_GROUP, true, null); producer.setNamesrvAddr(DEFAULT_NAMESRVADDR); producer.start(); for (int i = 0; i < 13; i++) { try { Message msg = new Message(TOPIC, TAG, "OrderID188", "Hello world".getBytes(StandardCharsets.UTF_8)); SendResult sendResult = producer.send(msg); System.out.printf("%s%n", sendResult); } catch (Exception e) { e.printStackTrace(); } } producer.shutdown(); } ` error log: ` ERROR MQTraceSendThread_0_1 - send trace data failed, the traceData is Pub1745947498841DefaultRegionProducerGroupNameTopicTest240E047CD8C94BA6F55B9B60C7894D91132818B4AAC295A639570000TagAmain_0192.168.255.186:1091119360C0A8FFBA00002A9F0000000000034D4Ftrue java.lang.IllegalStateException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to null failed at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:859) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:576) at org.apache.rocketmq.client.trace.AsyncTraceDispatcher$AsyncDataSendTask.tryGetMessageQueueBrokerSet(AsyncTraceDispatcher.java:414) at org.apache.rocketmq.client.trace.AsyncTraceDispatcher$AsyncDataSendTask.sendTraceDataByMQ(AsyncTraceDispatcher.java:368) at org.apache.rocketmq.client.trace.AsyncTraceDispatcher$AsyncDataSendTask.flushData(AsyncTraceDispatcher.java:351) at org.apache.rocketmq.client.trace.AsyncTraceDispatcher$AsyncDataSendTask.sendTraceData(AsyncTraceDispatcher.java:328) at org.apache.rocketmq.client.trace.AsyncTraceDispatcher$AsyncDataSendTask.run(AsyncTraceDispatcher.java:299) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:750) Caused by: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to null failed at org.apache.rocketmq.remoting.netty.NettyRemotingClient.invokeSync(NettyRemotingClient.java:584) at org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:2090) at org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:2081) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:798) ... 11 common frames omitted ` ### Steps to Reproduce 1. create a DefaultMQProducer and set traceEnable true; 2. send one message 3. shutdown producer immediately ### What Did You Expect to See? trace data send succeeded ### What Did You See Instead? trace data send failed ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
