>                 Key: HARMONY-2896
>                 URL: https://issues.apache.org/jira/browse/HARMONY-2896
>             Project: Harmony
>          Issue Type: Bug
>          Components: Classlib
>            Reporter: Ilya Okomin
>            Priority: Minor
>
> There is no mention of any exception in the specification.
> RI throws unspecified NPE for javax.swing.plaf.basic.BasicComboBoxUI.getAccessibleChildrenCount(null) while Harmony does not.
> Next test case passes on RI and fails on Harmony:
> --------- test.java ----------
> import javax.swing.plaf.basic.BasicComboBoxUI;
> import junit.framework.TestCase;
> import junit.textui.TestRunner;
> public class test extends TestCase {
>     public static void main(String args[]) {
>         TestRunner.run(test.class);
>     }
>     public void testRun() {
>         BasicComboBoxUI cb = new BasicComboBoxUI();
>         try {
>             cb.getAccessibleChildrenCount(null);
>             fail("NullPointerException expected");
>         } catch (NullPointerException e) {
>             // expected
>         }
>     }
> }
