[classlib][swing] j.s.text.BoxView.childAllocation does not throw NPE whereas RI does
-------------------------------------------------------------------------------------

                 Key: HARMONY-2776
                 URL: http://issues.apache.org/jira/browse/HARMONY-2776
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Alexey A. Ivanov
            Priority: Minor


Consider the following example:

import java.awt.Rectangle;

import javax.swing.text.BoxView;
import javax.swing.text.Element;
import javax.swing.text.PlainDocument;
import javax.swing.text.View;

public class Test {
    private static class BV extends BoxView {
        public BV(final Element element, final int axis) {
            super(element, axis);
        }

        @Override
        public void childAllocation(final int index, final Rectangle alloc) {
            super.childAllocation(index, alloc);
        }
    }

    public static void main(String[] args) {
        BV bv = new BV(new PlainDocument().getDefaultRootElement(), View.Y_AXIS);
        bv.childAllocation(0, null);
        System.err.println("silent");
    }
}
======= end of code =======

Harmony prints:
silent


RI prints:
java.lang.NullPointerException
	at javax.swing.text.BoxView.childAllocation(BoxView.java:669)
	at Test$BV.childAllocation(Test.java:59)
	at Test.main(Test.java:65)
