### 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 centos7 ### RocketMQ version 5.3.1及以上 ### JDK Version jdk8 ### Describe the Bug public Message request(final Message msg, long timeout) throws RequestTimeoutException, MQClientException, RemotingException, MQBrokerException, InterruptedException { long beginTimestamp = System.currentTimeMillis(); prepareSendRequest(msg, timeout); final String correlationId = msg.getProperty(MessageConst.PROPERTY_CORRELATION_ID); try { final RequestResponseFuture requestResponseFuture = new RequestResponseFuture(correlationId, timeout, null); RequestFutureHolder.getInstance().getRequestFutureTable().put(correlationId, requestResponseFuture); long cost = System.currentTimeMillis() - beginTimestamp; this.sendDefaultImpl(msg, CommunicationMode.ASYNC, new SendCallback() { @Override public void onSuccess(SendResult sendResult) { requestResponseFuture.setSendRequestOk(true); // 注意当broker写入成功后响应客户端，该方法会被调起，导致waitResponse直接返回，此时reply消息可能还未到达。应该将这行代码删除。 requestResponseFuture.acquireCountDownLatch(); } @Override public void onException(Throwable e) { requestResponseFuture.setSendRequestOk(false); requestResponseFuture.putResponseMessage(null); requestResponseFuture.setCause(e); } }, timeout - cost); return waitResponse(msg, timeout, requestResponseFuture, cost); } finally { RequestFutureHolder.getInstance().getRequestFutureTable().remove(correlationId); } } 这个方法会导致rpc调用还未等到超时时间就抛出RequestTimeoutException异常，原因：注意当broker写入成功后响应客户端，SendCallback.onSuccess方法会被调起，requestResponseFuture的锁提前释放，从而导致waitResponse直接返回，此时reply消息可能还未到达。 ### Steps to Reproduce 运行example工程下只启动RequestProducer，不启动ResponseConsumer，将超时时间设置为60s, 大概1s以内就会抛出描述中的异常。 ### What Did You Expect to See? 该方法用于实现rpc调用，期望在超时时间到达之前或者reply消息到达之前，不应该直接返回。 ### What Did You See Instead? 期望在超时时间到达之前或者reply消息到达之后，才返回相应结果。 ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
