Because I'm on the way to megre with libgcj's algorithm. This algorithm
needs the package-private members in other classes (RuleBaseCollator).
I wanna merge both algorithms as both have their good things.

After re-reading online API I think this has to be revisited too. I will
think about it and post a patch for confirmation later.
