> Testing observed a few failures after JDK-8276901. The reason for the failures is in the native-wrappers, in the +UseHeavyMonitors paths, we don't preserve the result register after the native call.
> 
> Testing:
>  - [x] java/awt/color, sun/java2d/cmm tests (x86_32, x86_64 x -UseHeavyMonitors, +UseHeavyMonitors)
>  - [ ] tier1 (x86_32, x86_64 x -UseHeavyMonitors, +UseHeavyMonitors)
