If you are in agreement, is it best to move this first step on and push it into hs-rt. I can then follow up with the additional steps: hotspot test updates in hs-rt, and the library changes in jdk9/dev, in parallel. I would have expected all changes to stay together in the same forest (hs-rt), so I'm not clear what additional library changes in jdk9/dev you are referring to here. It all looks fine to me too. Once this first phase gets to jdk9/dev then the rest of the library code using sun.misc.Unsafe can be switched to the jdk.internal version. They could move in the first phase too but that makes it a bigger patch so I think Chris has wisely limited the library changes to just those that are using methods that are new in 9.

Thanks Alan! Phased approach is perfectly fine and understandable, but waiting till phase 1 hits jdk9/dev will introduce a delay that need not occur if phase 2 also goes to hs-rt. Up to Chris of course - he may have other things to keep him busy until these changes propagate. :)

Thanks, David
