[jira] [Created] (KAFKA-16354) FinalizedFeatureChangeListenerTest should use mocked latches

Greg Harris created KAFKA-16354:
-----------------------------------

             Summary: FinalizedFeatureChangeListenerTest should use mocked latches
                 Key: KAFKA-16354
                 URL: https://issues.apache.org/jira/browse/KAFKA-16354
             Project: Kafka
          Issue Type: Test
          Components: core
    Affects Versions: 3.7.0
            Reporter: Greg Harris


testCacheUpdateWaitFailsForUnreachableVersion takes 30 seconds, and testInitFailureDueToFeatureIncompatibility takes 5 seconds. This appears to be caused by FeatureCacheUpdater#awaitUpdateOrThrow waiting for a real CountDownLatch with a real-time timeout.

Instead, a mocked latch should be used to exit the await immediately.

This should be done both for CPU-independence, and for test execution speed.
