--------------------------------
Resolution: Fixed
I just committed this. A tiny performance test shows an 8% boost to
serialization and a 15% boost to deserialization.

> TCompactProtocol currently uses a java.util.Stack of Shorts internally to
> manage its field id deltas. In some profiling, this seems to take more
> runtime than we'd like. It's probably due to the fact that we are boxing and
> unboxing the primitive shorts whenever we interact with the stack.
> Since we have pretty narrow needs for the stack, I think a purpose-built
> version could perform much better.
