the schema of LIST_OFFSETS consists of
- throttle_time_ms:INT32 and
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
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.
