Description ralphlevan 2015-11-18 18:27:22 UTC 
I have a trivial method that creates an ArrayList and returns it.  The declaration of the ArrayList gets an incorrect hint that "The collection is only added to, never read".

Here's the method:
        static List<Tuple> asList(Tuple[] t, int num) {
            ArrayList<Tuple> v=new ArrayList<Tuple>();
            for(int i=0; i<num; i++)
                v.add(t[i]);
            return v;
        }

I believe this problem is new in 8.1.

Thanks!

Ralph
