@harshach @HeartSaVioR I feel there's more to it than that. My assumption
now is only 1 field is declared because we're falling back to only
deserialising the message given a null key. If we were to declare both fields
the actual deserialisation should look like:
return new Values(key == null ? StringUtils.EMPTY : deserializeString(key),
deserializeString(value));
I'll adjust my PR if you agree that this is the way to go.
