> {{MessageInHandler.decode()}} occasionally reads the payload incorrectly,
> passing the full message to {{MessageIn.read()}} instead of just the payload
> bytes.
> You can see the stack trace in the logs from this [CI
> run|https://circleci.com/gh/iamaleksey/cassandra/437#tests/containers/38].
> {code}

> Reconstructed, truncated stream passed to {{MessageIn.read()}}:
> {{0000000b000743414c5f42414301002a01e1a5c9b089fd11e8b517436ee1243007040000005d10fc50ec}}
> You can clearly see parameters in there encoded before the payload:
> {{[43414c5f424143 - CAL_BAC] [01 - ONE_BYTE] [002a - 42, payload size] 01 e1
