I verified that changing compareAndSwap to compareAndSet in that code allow to pass AOT jtreg tests. Thank you Dean.

May be that is causing the assert but there are other places in Graal which may use jdk.internal.misc.Unsafe.compareAndSwap* methods according to 'grep' and have to be fix.

Is this the problem: https://github.com/graalvm/graal/blob/1c5e3a5e544335e85dd271853161bceb635ac376/compiler/src/org.graalvm.compiler.replacements/src/org/graalvm/compiler/replacements/StandardGraphBuilderPlugins.java#L251

ILW = Tests fail because Unsafe method is not found, AOT tests with '-ea -esa', no workaround = MMH = P3

JDK-8159995 did not fix Graal or JVMCI. It only fixed test: src/jdk.internal.vm.compiler/share/classes/org.graalvm.compiler.hotspot.test/src/org/graalvm/compiler/hotspot/test/CheckGraalIntrinsics.java
