> Harmony's Arrays.binarySearch(Object[],Object o) will throw ClassCastException when second parameter does not implement Comparable interface.
> It means that RI will call compareTo from the first parameter rather than the second parameter.
> Here is the test case
> ---------------------------------
> public class MethodTest extends TestCase {
> public void testMethod() throws Exception{
> Object object = new Object();
> Object[] objects = new MockComparable[] { new MockComparable() };
> assertEquals("Should always return 0", 0, Arrays.binarySearch(objects, object));
> }
>
> static class MockComparable implements Comparable{
> public int compareTo(Object o) {
> return 0;
> }
> }
> }
> ------------------------------
> Result:
> RI passed
> Harmony failed
