I can certainly believe that:  invokeGeneric is not fully implemented yet.

Try this instead:
	lookup.put(String.class, func.asType(func.type().generic()));

Then you can call any handler with a fast exact call:
	lookup.get(x.getClass()).invoke(x);  // x must be an Object

P.S. The name MH.invoke will be changing to MH.invokeExact, to emphasize the difference from invokeGeneric.
