[GitHub] [kafka] mimaison commented on pull request #12350: KAFKA-13856:MirrorCheckpointTask meets ConcurrentModificationException

   @Justinwins Have you actually seen this exception in practice? `idleConsumerGroupsOffset` is used by 2 threads, one reader and one writer. The thread reading it, `syncGroupOffset`, does not iterate the map and only does lookups.
