null
------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2618
                 URL: http://issues.apache.org/jira/browse/HARMONY-2618
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Pavel Dolgov


Problem details:
----------------------
According to J2SE API 5.0 specifications of
getExpandedDescendants() method: 
"Returns an Enumeration of the descendants of the path parent that are
currently expanded.If parent is not currently expanded, this will return null"
javax.swing.JTree.getExpandedDescendants() returns Enumeration of TreePath
while RI returns null.

Test for reprodicing:
--------------------------
import javax.swing.JTree;
import javax.swing.tree.TreePath;
import junit.framework.TestCase;

public class TheTest extends TestCase {
    public void testcase1() {
        TreePath p = new TreePath(new Object());
        JTree t = new JTree();
        assertNull(t.getExpandedDescendants(p));
    }
}
