MethodHandle.invoke[Exact|Generic] doesn't throw UnsupportedOperationException if invoked via java.lang.reflect.Method.invoke.

The javadoc for the MethodHandle invokeExact/invokeGeneric methods states as follows:
  "When this method is observed via the Core Reflection API, it will appear as a single
  native method, taking an object array and returning an object. If this native method
  is invoked directly via Method.invoke ... it will throw an UnsupportedOperationException."

However, InvocationTargetException is thrown in such cases.
