>      Project: Harmony
>         Type: Bug

>   Components: Non-bug differences from RI

> The following code
> import java.text.*;
> public class Test  {
>   public static void main (String[] args) throws Exception {                 
>     new RuleBasedCollator("< a").compare(null, null);
>   } 
> } 
> throws NPE on RI and doesn't throw on Harmony . If one of arguments is not null, both
implementations throw NPE so I believe it's better to follow RI and add NPE in case of both
nulls. Please see the patch with unit test and code patch attached.
