I think it's a burden cos you're forcing client to either accept 
Class<?> or cast to Class. Example:

A method defined as:

public static List<Class<?>> infinispanClasses();

Any client needs to do:

List<Class<?>> ispnClasses = ClassFinder.infinispanClasses(cp);

A client can't do:

List<Class> ispnClasses = ClassFinder.infinispanClasses(cp);

I see that as a burden on the client cos you're forcing the client to 
deal with generics that say nothing.
