@Test(dataProvider = "accessModesProvider", expectedExceptions = IllegalArgumentException.class)
public void methodInvocationFromMethodInfo(VarHandle.AccessMode accessMode) throws Exception {
VarHandle v = handle();
// Try a reflective invoke using a Method obtained from cracking
// a MethodHandle
MethodHandle mh = MethodHandles.lookup().unreflect(
VarHandle.class.getMethod(accessMode.methodName(), Object[].class));
