Make map in NotificationContext synchronized One issue we observed is that when batch messages enabled, it will have NPE in ZNRecord merge record. Race condition could be the root cause. The only place can have race condition is the current state update map in NotificationContext, which is passed as input for multiple sub tasks in BatchMessageHandler.
