> Re-authenticating causes mismatched parse of response

> Key: KAFKA-9854
> URL: https://issues.apache.org/jira/browse/KAFKA-9854
> Project: Kafka
> Issue Type: Bug
> Reporter: Chia-Ping Tsai

> Priority: Critical
> Fix For: 2.6.0, 2.5.1
>
>
> the schema of LIST_OFFSETS consists of
> # throttle_time_ms:INT32 and
> # responses:ARRAY
>
> If throttle_time_ms is zero and size of responses is small enough, its
> binary is compatible to schema of SASL_HANDSHAKE composed of
> # error_code:INT16 and
> # mechanisms:ARRAY(STRING)
>
> Hence, there is no Schema error when SASL_HANDSHAKE tries to parse response
> of LIST_OFFSETS but the check of correction id throws IllegalStateException
> due to mismatched error. The IllegalStateException is NOT caught and the
> mismatched response is not sent back to Selector so the cascading error
> happens that all following responses are parsed by incorrect Schema.
