> Issue Type: Bug
> Components: streams, tools
> Affects Versions: 3.4.0
> Reporter: Jørgen
> Priority: Major

> When running the command _kafka-streams-application-reset --bootstrap-servers
> $BOOTSTRAP --application-id foo_ all internal topics that _starts with_ foo
> is deleted. This happens even if there's no application-id named foo.
> Example:
> {code:java}
> Application IDs:
> foo-v1
> foo-v2
> Internal topics:
> foo-v1-repartition-topic-repartition
> foo-v2-repartition-topic-repartition
> Application reset:
> kafka-streams-application-reset --bootstrap-servers $BOOTSTRAP
> --application-id foo
> > No input or intermediate topics specified. Skipping seek.
> Deleting inferred internal topics [foo-v2-repartition-topic-repartition,
> foo-v1-repartition-topic-repartition]
> Done.{code}
> Expected behaviour is that the command fails as there are no application-id's
> with the name foo instead of deleting all foo* topics.
> This is critical on typos or if application-ids starts with the same name as
> others (for example if we had foo-v21 and wanted to reset foo-v2)
> The bug should be located here:
> [https://github.com/apache/kafka/blob/c14f56b48461f01743146d58987bc8661ba0d459/tools/src/main/java/org/apache/kafka/tools/StreamsResetter.java#L693]
> Should check that the topics matches the application-id exactly instead of
> checking that it starts with the application-id.
