[aspectj-users] Can an around advice for a constructor return a different Class of object?

I have a framework that I would like to use, that generates a bunch of
ArrayList objects, what I would like to do is to trap the constructor calls
and replace the ArrayList with another type of List.  Is this possible?
Basically, I want to create a ListFactory by using aspects.

This is what I have currently:
Object around(int capacity): call(!NSArray+ && List+.new(int)) &&
within(org.objectstyle..*) && args(capacity){
        return new

However, I am getting a ClassCastException.  The NSMutableArray implements
the List interface.

Thanks for any help.
