There isn't anything to widen to; the only thing that a short can be boxed to is Number (Short is a subclass of Number).

And please use the code tags; I have added them and you can see how much easier it is to read.

A short can never be converted into an Integer, so all that remains is Short, Number or Object.

You can't widen then box, only box then widen
