Senaka, You are making a good progress with building Harmony GC separately from Harmony VM.
I have a piece of advise concerning the focus of the task. While include list minimization is interesting, I don't think you should spend too much time on it. If something is required, keep it, and keep all things it depends on. To convince perfectionist in you I would say that the further code changes would be much greater, and big parts would be efficiently removed due to logic changes. The things I would recommend you to throw away are files in Java. Thanks.
