HV-912 Alternative approach

@emmanuelbernard, this is the brute-force alternative which removes all the RH methods and pushes the invocations to the callers. There is one method left-over though (loadClass()). The required duplication for this made me think about alternatives. But given the issues around the ACC, maybe we should go for it nevertheless to have a fix?
I think I prefer an actual prosa comment that this should be only package visible
