### 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 all ### RocketMQ version latest ### JDK Version all ### Describe the Bug I found a npe bug in method getAndCreateChannel.  It may caused by 'getAndCreateChannelAsync(addr).awaitUninterruptibly()' in method getAndCreateChannel.  Since channelFuture has got from getAndCreateChannelAsync and is judged not null, why not use channelFuture instead of getAndCreateChannelAsync again? ### Steps to Reproduce start broker ### What Did You Expect to See? no npe bug ### What Did You See Instead? an npe bug ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
