I did some checking. It looks ok, the filterReturnValue does go through the editor, and two method handles such as say:

MethodHandle mh1 = VT_Interval.findConstructor(MethodHandles.lookup(),
                                              MethodType.methodType(void.class, int.class, int.class));

MethodHandle mh2 = VT_Interval.findConstructor(MethodHandles.lookup(),
                                              MethodType.methodType(void.class, int.class, int.class));

will share the same lambda form even though the MH instances are different.
