> Harmony: classlib + VM revision 421248
> If we try to find a non-comparable item in an empty array, RI returns -1 while Harmony throws ClassCastException. 
> Code to reproduce:
> import java.util.*;
> public class Test {
>     public static void main (String[] args) {  
>         System.err.println(Arrays.binarySearch(new Object[] {}, new Object()) == -1 ? "PASSED" : "FAILED");
>     } 
> }
> -------
> Please see the patch with unit test for this case and fix for classlib code attached
