> 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
