--------------------------------

I wonder if Jay can provide a bit more information so that I can start looking at this and working on providing patch?

> The common package introduced a better way of defining requests using a new protocol definition DSL and also includes wrapper objects for these.
> We should switch KafkaApis over to use these request definitions and consider the scala classes deprecated (we probably need to retain some of them for a while for the scala clients).
> This will be a big improvement because
> 1. We will have each request now defined in only one place (Protocol.java)
> 2. We will have built-in support for multi-version requests
> 3. We will have much better error messages (no more cryptic underflow errors)
