-------------------------------------
This also applies to the other mechanims in the code base.
> SASL mechanisms that do support neither integrity nor confidentality should
> throw exception on wrap/unwrap

> Key: KAFKA-18064
> URL: https://issues.apache.org/jira/browse/KAFKA-18064
> Project: Kafka
> Issue Type: Bug
> Components: security
> Reporter: Istvan Toth
> Priority: Major
>
> wrap/unwrap should throw an exception unless a non-auth QOP has been
> negotiated.
> SCRAM only supports auth QOP, so wrap/unwrap should always throw
> IllegalStateException.
