>             Project: Kafka
>          Issue Type: Bug

>            Priority: Major
>
> `KafkaApis.handle` uses the following logic to validate the envelope:
> ```
>       request.envelope.foreach { envelope =>
>         if (maybeHandleInvalidEnvelope(envelope, request.header.apiKey)) {
>           return
>         }
>       }
> ```
> Since this is a non-local return, scala raises an exception, which then causes `handleError` to get invoked, which sends an error response.
