This is great work - thank you for doing this.
As the majority of the changed code is in the 2d/awt/client area then I
hope that you will get timely reviews from those areas. The main thing
with a change like this is that the changes build on all platforms and
I've know you've verified that.
I skimmed through the webrev and don't see anything obviously wrong. I
focused mostly on the non-client code and they all look right. It's
interesting that @GenerateNativeHeader was added to several classes with
native methods, I don't know why that was the case. I was also unaware
that we had Haskell code in the build.
So thumbs up from me. I assume you or Jon will remove
GenerateNativeHeader from the langtools repository once your changes are
