    Description

      We're seeing an issue where an exception inside the main processing loop of a consumer doesn't cause the JVM to exit, as expected (and, in our case, desired). From the thread dump, it appears that what's blocking exit is the "kafka-coordinator-heartbeat-thread", which is not currently a daemon thread. Per the mailing list, it sounds like this is a bug.
