Matthias J. Sax resolved KAFKA-13400.
-------------------------------------
Resolution: Not A Bug
Based on the information provided, the conclusion seems to be that a state
store handle is passed to a different thread, and that the state store is
accessed from outside of the `StreamThread` context. – This is an invalid usage
pattern, and thus there seems to be no bug in Kafka Streams.
> offset() is not supported in standby tasks.
