Description

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

• JUnit test for the problem
