### 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 Don't care. ### RocketMQ version branch: 4.9.x ### JDK Version Don't care. ### Describe the Bug `org.apache.rocketmq.remoting.netty.NettyRemotingAbstract#invokeSyncImpl` ```java channel.writeAndFlush(request).addListener(new ChannelFutureListener() { @Override public void operationComplete(ChannelFuture f) throws Exception { if (f.isSuccess()) { responseFuture.setSendRequestOK(true); return; } else { responseFuture.setSendRequestOK(false); } responseTable.remove(opaque); responseFuture.setCause(f.cause()); responseFuture.putResponse(null); log.warn("send a request command to channel <" + addr + "> failed."); } }); RemotingCommand responseCommand = responseFuture.waitResponse(timeoutMillis); ``` `org.apache.rocketmq.remoting.netty.ResponseFuture#putResponse` ``` public void putResponse(final RemotingCommand responseCommand) { this.responseCommand = responseCommand; this.countDownLatch.countDown(); } ``` 1. `responseFuture.waitResponse(timeoutMillis);` -> `this.countDownLatch.await(timeoutMillis, TimeUnit.MILLISECONDS);` use `countDownLatch` to wait for asynchronous response. 2. If `f.isSuccess() == false`, then call `responseFuture.putResponse(null);` to `countDownLatch.countDown()`. 3. But if `f.isSuccess() == true`, did not to `countDownLatch.countDown()`, cause `responseFuture.waitResponse(timeoutMillis);` always timeout after `timeoutMillis`. ### Steps to Reproduce Don't care. ### What Did You Expect to See? If `f.isSuccess() == true`, also `countDownLatch.countDown()`. And `RemotingCommand responseCommand = responseFuture.waitResponse(timeoutMillis);` is no need to wait for timeout. ### What Did You See Instead? Nothing. ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
