The wrappers must still wrap the abstract classes, even if they can't
instantiate them.  This is the only way that they can wrap the methods
defined in abstract classes.  It's also necessary for the wrappers to
wrap the abstract classes so that they can trace the hierarchy
backwards to the parent classes of each abstract class.
