The methods in HotSpotJVMCIRuntime converting a ResolvedJavaMethod to an Executable[1] and a ResolvedJavaField to a Field[2] will crash in jargraal if passed a <clinit> method or an internal field[3].

For example, when trying to get the mirror for the java.lang.Thread.jvmti_thread_state injected field[4]:

#
# A fatal error has been detected by the Java Runtime Environment:
