PageRanges(null) throws IllegalArgumentException instead of NullPointerException

Name: ooR10006 Date: 04/03/2001


The spec for constructor javax.print.attribute.standard.PageRanges(int[][] members)
says:
"Throws:
 NullPointerException - (unchecked exception) Thrown if members is null or any
 element of members is null."

But in Merlin b58 API implementation of PageRanges((int[][])null)
throws IllegalArgumentException.

The following test shows this:

import javax.print.attribute.standard.PageRanges;

public class Test {
    public static void main(String[] args){
        try {
            int[][] m = null;
            PageRanges pr = new PageRanges(m);
            System.out.println("wrong: no exceptions, NullPointerException expected");
        } catch (NullPointerException e){
            System.out.println("OKAY");
        } catch (IllegalArgumentException ie){
            System.out.println("wrong: IllegalArgumentException");
        }
    }
}

The error is in JDK1.4 source code of PageRanges(int[][] members) constructor:

    public PageRanges(int[][] members) {
super (members);
if (members == null) {
throw new IllegalArgumentException("members is null");
}
    ...
