Nathan Beyer commented on HARMONY-1144:
---------------------------------------

I've applied the patch and tweaked a few things (spelling errors, etc). Please check out the code and make sure it looks okay. I'm still trying to figure out how to add a test of some sort for this, but if you can figure it out first, please post a patch.

> 1. I added getFieldOffset method to o.a.h.util.concurrent.Atomics.java
> 2. Atomics.compareAndSet* were modified for using offset instead of Field
> 3. Corresponding methods in Unsafe stub were implemented, other were modified to throw UnsupportedOperationException.
> I dowloaded and ran JSR166_PFD unit tests. All of them, except depending on unimplemented methods in Unsafe, are passed.
> Please try it.
