Comment 2 Milos Kleint 2010-02-22 01:03:16 UTC 
a lookup impl problem? reassigning for evaluation.
Comment 3 Jaroslav Tulach 2010-03-12 13:20:59 UTC 
Not a problem in Lookup. This is the code:

        public SimpleItem(T obj) {
            if (obj == null) {
                throw new NullPointerException();
            }
            this.obj = obj;
        }
