[jira] Created: (HARMONY-2618) [classlib][swing]
javax.swing.JTree.getExpandedDescendants() returns Enumeration while RI
returns null
[classlib][swing] javax.swing.JTree.getExpandedDescendants() returns Enumeration while RI returns 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));
}
}

Sergey Krivenko commented on HARMONY-2618:
------------------------------------------
It looks like the JTreeTest is invalid. Its testGetExpandedDescendants() method contains the following code:
assertFalse(tree.getExpandedDescendants(path1).hasMoreElements());
assertFalse(tree.getExpandedDescendants(path11).hasMoreElements());
This code throws NullPointerException on RI. The spec explains why: method getExpandedDescendants(TreePath parent) should return null if its parameter is not currently expanded. Which is the case.
