Description
While running some JMH where graal, java.base, and jvmci are AOTed, an exception happens:

REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on
why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial
experiments, perform baseline and negative tests that provide experimental control, make sure
the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts.
Do not assume the numbers tell you what you want them to tell.

ILW = Incorrect execution of compiled code (exception is thrown), with AOT'ed Graal, java.base and jvmci, don't use AOT = HLM = P3

The exception is thrown from a class initialization call. This should have a very much fixed position in the graph. Not sure why would the failure happen...

Problematic method: jdk.vm.ci.services.JVMCIServiceLocator.getProviders(Ljava/lang/Class;)Ljava/util/List; The immediately obvious problem, is that we call to runtime to resolve "Lorg/graalvm/compiler/hotspot/HotSpotGraalJVMCIServiceLocator$Shared;" and it fails and we throw an exception. Prior to JDK-8206992 that contains my fix to forward exceptions during initialization we would silently deopt and retry in the interpreter. Now we don't and just forward the exception. Also, we seem to be inlining HotSpotGraalJVMCIServiceLocator.getProvider() into JVMCIServiceLocator.getProviders(), which is odd, we seem to use profiling information? We should be ignoring it.

[~iveresov] please, look Failed in static access: void onCompilerCreation(HotSpotGraalCompiler compiler) { Shared.SINGLETON.onCompilerCreation(compiler); } public final class HotSpotGraalJVMCIServiceLocator extends JVMCIServiceLocator { /** * Holds the state shared between all {@link HotSpotGraalJVMCIServiceLocator} instances. This is * necessary as a service provider instance is created each time the service is loaded. */ private static final class Shared { static final Shared SINGLETON = new Shared();
