### 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 OS:openEuler22.03(LTS-SP3) ### RocketMQ version version:rocketmq-all-5.3.1 ### JDK Version Run:openjdk 1.8.0_432 ### Describe the Bug In the same ConsumerGroup, the Consumer instances have different Topics subscribed to do not work on the 5.2.0 SDK. ### Steps to Reproduce I started two consumer instances with the same consumer group configuration, subscribing to different topics separately. However, the subscription relationship was inconsistent, resulting in chaotic and lost consumer messages. As described in the official documentation, the 5. x version SDK does not support consumer instances under the same consumer group subscribing to different topics. ### What Did You Expect to See? The 5.x version of the SDK supports Consumer instances in the same ConsumerGroup subscribing to different topics. ### What Did You See Instead? ![image](https://github.com/user-attachments/assets/22380261-84ba-4224-a5f4-293f5f387063) ![image](https://github.com/user-attachments/assets/0c7aee5b-d7ef-4fe7-946d-a307ca0266e6) ![image](https://github.com/user-attachments/assets/a2935463-a154-471c-a31f-185b2707527f) ### Additional Context I developed in the springboot environment, version 2.7.18,and the version of rocketmq-spring-boot-starter is 2.3.0. -- This is an automated message from the Apache Git Service.
