Huh... that's interesting.  I wonder why Arrays.sort(int[]) is all
in-place but sort(Object[]) is not.

I was wondering that myself. Here's the code:

   public static <T> void sort(T[] a, Comparator<? super T> c) {
   T[] aux = (T[])a.clone();
       if (c==null)
           mergeSort(aux, a, 0, a.length, 0);
       else
           mergeSort(aux, a, 0, a.length, 0, c);
   }
