Description

I have observed the following exception to kill a thread in the current trunk of Streams:

[2020-03-19 07:04:35,206] ERROR [stream-soak-test-e60443b4-aa2d-4107-abf7-ce90407cb70e-StreamThread-1] stream-thread [stream-soak-test-e60443b4-aa    2d-4107-abf7-ce90407cb70e-StreamThread-1] Encountered the following exception during processing and the thread is going to shut down:  (org.apache.kafka.streams.processor.internals.StreamThread)
java.lang.IllegalStateException: The changelog reader is not restoring active tasks while trying to transit to update standby tasks: {}
        at org.apache.kafka.streams.processor.internals.StoreChangelogReader.transitToUpdateStandby(StoreChangelogReader.java:303)

        at org.apache.kafka.streams.processor.internals.StreamThread.runLoop(StreamThread.java:498)
        at org.apache.kafka.streams.processor.internals.StreamThread.run(StreamThread.java:472)

Judging from the fact that the standby tasks are reported as an empty set, I think this is just a missed case in the task manager. PR to follow shortly.
