> Problem:
> Some Collections.checked... methods throw NPE if one of their arguments is null in RI
but don't throw in Harmony
> Code to reproduce:
> import java.util.*;
> public class Test {
>     public static void main (String[] args) {  
>            try {
>                Collections.checkedSortedMap(new TreeMap(), null, Short.TYPE);
>                System.err.println("fail 1");
>            } catch (NullPointerException e) {
>            }
>            try {
>                Collections.checkedSortedMap(new TreeMap(), Float.TYPE, null);
>                System.err.println("fail 1.1");
>            } catch (NullPointerException e) {
>            }
>            try {
>                Collections.checkedMap(new TreeMap(), null, Float.TYPE);
>                System.err.println("fail 2");
>            } catch (NullPointerException e) {
>            }
>            try {
>                Collections.checkedMap(new TreeMap(), Float.TYPE, null);
>                System.err.println("fail 2.2");
>            } catch (NullPointerException e) {
>            }
>            try {
>                Collections.checkedCollection(new Stack(), null);
>                System.err.println("fail 3");
>            } catch (NullPointerException e) {
>            }            
>     } 
> }
> in RI this test prints nothing, in Harmony all 'fail' messages are printed
> Please see the patch attached. It contains:
> - JUnit test for the problem
> - patch for java.util.Collections
