Tim Ellison commented on HARMONY-22:
------------------------------------

The rules for (object) Double/Float comparison differ from those for (JLS 
floating-point) double/float types.
This provides for the natural ordering of the object types (c.f. their 
implementation of equals(Object) that also differs from JLS types).

> Double NaN should compare greater than positive infinity

> java.lang.Double.compareTo(java.lang.Double) should answer that  Double.NaN 
> is greater than Double.POSITIVE_INFINITY.
> Here's a test case that demonstrates the problem:
>       public void testDoubleCompare() {
>               Double nonNumber = new Double(Double.NaN);
>               Double infinity = new Double(Double.POSITIVE_INFINITY);
>               int indicator = nonNumber.compareTo(infinity);
>               assertEquals("Incorrect comparison result", 1, indicator);
>       }
