Thank for your reply @Stephan14. `responseCallback` is called from: https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/group/GroupMetadataManager.scala#L323 where it is called by the same thread or https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/group/GroupMetadataManager.scala#L339 where it is called with delayed produce by a different thread. In this scenario, we explicitly say that the completion of this response should be called in scope of delayedProduceLock which we set to group.lock at https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/group/GroupMetadataManager.scala#L338 Hence, the other thread will acquire the lock on `group` before calling the `responseCallback` What am I missing here? -- This is an automated message from the Apache Git Service.
