@dajac Thanks for your reviewed. Normally, this value(`group.groupState()`) is the network request processed by the customer in the cluster when sending the consumergroups message. Normally, the response will carry this value. If this value is not set, `group.groupStat ()` will be a null. This way of writing `group.groupState().Equals (‘’)` will report null pointer exception. You can try to do this and you'll see this.` org.apache.kafka . clients.admin.KafkaAdminClientTest#testListConsumerGroupsWithStates` `Change to setgroupstate ("stable") ==> setgroupstate (null)` However, according to the normal design, the `response` without `groupstate` itself is illegal, and it is reasonable not to handle this response. Even if NPE occurs, this method is in the outer try catch and will not cause system crash. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
