Armin Braun commented on KAFKA-3874:
------------------------------------

I think this one is still pretty flaky. I see this 
(https://builds.apache.org/job/kafka-pr-jdk8-scala2.12/2032/) kind of failure a 
lot locally and on Jenkins.
Should we reopen this one maybe? Or add a new JIRA since the way it fails 
appears to have changed to:

{code}
