Answer 1

Have you seen this code fragment ?

    @Override
    public Result authenticate(HttpExchange he) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

It's precisely the one that will throw the aforementionned exception each time you try to authenticate.

So, to my mind, the solution to your authentication problem is quite simple : implement this method.
