i'm trying to create a type L that extends a List containing elements of type E.

I can't create an instance in the above example.. Anyone has some pointers or an example of how to go about this?

If I'm not mistaken, this is unfortunately not possible, because of the way Java generics currently work (with type erasure).

See this from Angelika Langer's excellent Java Generics FAQ:
Can I create an object whose type is a type parameter?
