The REST client code, as such, is meant just to debug the server components, and is used by unit tests, and is not meant as any kind of "official" REST client, and this explains why there has been no such care taken. We've talked before about moving these classes from src/main/ to src/test/ and that should have been done to avoid this kind of confusion.
