Yeah, I can see that would be an issue, from a strictly coding 
perspective.  Does this work:

   List<Class<?>> = (List<Class<?>>) (new List());

?  Seems like it should, but I haven't played around with casting and 
parameterized types either.  Obviously, it could throw runtime errors if 
the new list has items that are not Class<?> added somewhere else, but 
one has to presume some competence on the part of the coder too.
