Reflection and generics

Question

Hi all:
I am working with the generic and reflection stuff. Well the problem is that in one of my clases I have a data
private Vector<nAryNode<T>> childs;
.....where nAryNode<T> is a class I created using generics.
Now when I want to initialize my childs variable, well the easy thing to do is:
childs = new Vector<nAryNode<T>>(3)But I want to initialize it using reflection and my code is:
        Class v = Class.forName("java.util.Vector");
        Class[] argVector = new Class[] {int.class};
        Constructor consVector = v.getConstructor(argVector);
        Object[] arguments = new Object[] {new Integer(n)};
        childs = (Vector<nAryNode<T>>)consVector.newInstance(arguments);Finally when I compile I got the annoying warning message
nAryNode.java:29: warning: [unchecked] unchecked cast
found : java.lang.Object
required: java.util.Vector<nAryNode<T>>
childs = (Vector<nAryNode<T>>)consVector.newInstance(arguments);
^
Well my program can run, but I would like to make disappear that message. Please if you have any suggestions for me, it will be great. Thx

AFAIK, there is no solution to this currently because arrays of generic types are not allowed. Therefore "consVector.newInstance(arguments);" return a Vector and cannot be made to return "Vector<Integer>" (or whatever)
