---------------------------------------------------------------------
So interestingly I worked on another ticket that reported the exact same test
as being flaky (see https://issues.apache.org/jira/browse/KAFKA-13531) and I
couldn't reproduce any flakiness (hence the reason why that ticket is closed).
I rebased my fork of Kafka to the latest version in trunk and started running
this test and so far I have 1.6k runs without a failure (continuously running
the tests in loop as I post this comment).
[~cadonna] Would it be possible to state how you are running the tests and also
which JDK version (and which branch if you are not running latest trunk?).
Personally I am using Java 16 and to run the tests I am using the JUnit (not
gradle) runner with Intellij (primarily because it gives the ability to run a
test until it fails).
