>                 Key: KAFKA-5603
>                 URL: https://issues.apache.org/jira/browse/KAFKA-5603
>             Project: Kafka
>          Issue Type: Bug
>          Components: streams
>    Affects Versions:
>            Reporter: Matthias J. Sax
>            Assignee: Matthias J. Sax
>            Priority: Critical
>             Fix For:
> The contract of the transactional producer API is to not call any transactional method
after a {{ProducerFenced}} exception was thrown.
> Streams however, does an unconditional call within {{StreamTask#close()}} to {{abortTransaction()}}
in case of unclean shutdown. We need to distinguish between a {{ProducerFenced}} and other
unclean shutdown cases.
