In MirrorCheckpointTask.java, the field private Map<String, List<Checkpoint>> checkpointsPerConsumerGroup = new HashMap<> may be modified ( used with put API) , and traversed by two different threads at the same time. Clearly,this would incur ConcurrentModificationException. This bug still exists in Trunk branch. -- This message was sent by Atlassian Jira (v8.20.7#820007)
