-------------------------------------------------

             Summary: NullPointerException in ConsumerCoordinator
                 Key: KAFKA-5882
                 URL: https://issues.apache.org/jira/browse/KAFKA-5882
             Project: Kafka
          Issue Type: Bug
            Reporter: Seweryn Habdank-Wojewodzki


It seems bugfix [KAFKA-5073|https://issues.apache.org/jira/browse/KAFKA-5073] is made, but introduce some other issues.
In some cases (I am not sure which ones) I got NPE (below).

I would expect that even in case of FATAL error anythink except NPE is thrown.
