### 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-clients/discussions). - [X] I have searched the [GitHub Issues](https://github.com/apache/rocketmq-clients/issues) and [GitHub Discussions](https://github.com/apache/rocketmq-clients/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. ### Programming Language of the Client Java ### Runtime Platform Environment macos ### RocketMQ Version of the Client/Server The latest version ### Run or Compiler Version JDK 17 ### Describe the Bug Before the PushConsumer is launched, if the queue already contains some data, the subsequent launch of the PushConsumer will consume messages asynchronously until the remote configuration is synchronized with the local configuration, returning to normal state. ### Steps to Reproduce Before starting the PushConsumer, send some messages using a FIFO producer, such as numbers 1-10. After sending is complete, start the PushConsumer. At this point, you will notice that the messages are out of order. Then, try sending some more messages. This time, they will be normal and non-concurrent. ### What Did You Expect to See? Sequential output messages ### What Did You See Instead? When consuming messages for the first time, they are out of order. ### Additional Context 17:24:42.443 [RocketmqMessageConsumption-0-28] INFO PushConsumerTest - message=1 17:24:42.443 [RocketmqMessageConsumption-0-32] INFO PushConsumerTest - message=5 17:24:42.443 [RocketmqMessageConsumption-0-31] INFO PushConsumerTest - message=4 17:24:42.443 [RocketmqMessageConsumption-0-36] INFO PushConsumerTest - message=9 17:24:42.443 [RocketmqMessageConsumption-0-29] INFO PushConsumerTest - message=2 17:24:42.443 [RocketmqMessageConsumption-0-30] INFO PushConsumerTest - message=3 17:24:42.443 [RocketmqMessageConsumption-0-35] INFO PushConsumerTest - message=8 17:24:42.443 [RocketmqMessageConsumption-0-33] INFO PushConsumerTest - message=6 17:24:42.443 [RocketmqMessageConsumption-0-34] INFO PushConsumerTest - message=7 -- This is an automated message from the Apache Git Service.
