On virtual machines and expected behaviour

Ever tried running this on your ENTERPRISE VIRTUAL MACHINE?
Integer a = 1000;
 Integer b = 1000;
 System.out.println("a == b (1000 == 1000): " + (a == b));

 Integer aa = 100;
 Integer bb = 100;
 System.out.println("aa == bb (100 == 100): " + (aa == bb));
Guess what's the output, run it and report back.

I'm the idiot?  Run my test; run other tests.

In fact, give me one instance where a correctly-initialized Java non-primitive correctly compares against another correctly-initialized Java non-primitive using a == b and returns true if both non-primitives contain the same data.
