> AOT jtreg tests fail due to 8159995 [1] changes which renamed some methods in jdk.internal.misc.Unsafe
> The fix does renaming in Graal code which use jdk.internal.misc.Unsafe. It should go through Graal-core review process and pushed there (Oracle Labs repository) first. Doug, please, help with it.
> Note, JDK 9 will be updated soon [2] to get the same renaming so Graal-core does not need to check for JDK 10 specifically. But changes should be pushed only after [2] is pushed into jdk9/dev and get into promoted build which people use with Graal.

[2] is now pushed to 9.


> Second note. The copy of Graal-core in jdk9 (jdk.internal.vm.compiler) will be fixed by [2] changes.
> I looked on other places in Graal where such methods are used and they are from sun.misc.Unsafe class. Those places have to be fixed too when sun.misc.Unsafe become obsolete.
