getSuperClass() on arrays returns the wrong value

If you create an array of Integer, getClass().getSuperClass() returns Object's class
object. But if you ask if that array is an instanceof Number[], the answer is true.
The second answer makes the most sense, since an Integer[] object acts as if it
extends Number[]. It would seem that getSuperClass() of an array object should
return a class object for an array of the element's superclass, and not return Object.
