> Environment: Windows XP professional
> Reporter: Anton Luht
> Priority: Minor

> Build: classlib+VM revision 421248 msvc debug
> 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
