I tried that but it does not work.  I get an error on invokeExact (and I think I can't use invokeGeneric):

Exception in thread "main" java.dyn.WrongMethodTypeException: ()V cannot be called as ()Z

for:

  assertEquals(false, (boolean) mh.invokeExact());  // void -> boolean

Yeah, that would help me a lot :-)
