### Before Creating the Bug Report - [x] I found a bug, not just a question. - [x] I searched open GitHub Issues and pull requests and found no duplicate. - [x] I confirmed that this bug belongs to Apache RocketMQ. ### Runtime platform environment macOS (Darwin), reproduced with an isolated local unit test. ### RocketMQ version Branch: develop Git commit: fd0c95920e0deac96ce2ae27442747cc5e65e930 ### JDK Version Zulu OpenJDK 8 (8.94.0.17) ### Describe the Bug BrokerIdentityInfo supports partial identities: RaftReplicasInfoManager creates instances with null clusterName and brokerId. However, equals calls equals directly on every field, so comparing two valid partial identities throws NullPointerException. hashCode is already null-safe. ### Steps to Reproduce 1. Create two BrokerIdentityInfo instances with null clusterName, brokerName set, and null brokerId. 2. Call equals between them. 3. Observe NullPointerException. ### What Did You Expect to See? Two equivalent partial identities should compare equal and remain consistent with hashCode. ### What Did You See Instead? equals dereferences nullable fields and throws NullPointerException. ### Additional Context Complete identities, partial identities, and differing fields can all be covered with a small unit test. -- This is an automated message from the Apache Git Service.
