A DESCRIPTION OF THE REQUEST :
Currently, JSeparator does not support the MenuElement interface. JSeparator should be retrofitted to implement the interface so that operations performed on MenuElements do not need to treat them specially.

JUSTIFICATION :
Because JSeparator does not support the MenuElement interface, some operations treat them differently than "normal" menu elements. For example, when traversing a JMenu's elements using JMenu.getSubElements() and then MenuElement.getSubElements(), a null will appear whereever a JSeparator exists because it does not implement MenuElement.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JSeperator.getComponent: Return component from JSeperator's UI
JSeperator.getSubElements: Return zero length array
JSeperator.menuSelectionChanged: No-op
JSeperator.processKeyEvent: No-op
JSeperator.processMouseEvent: No-op

Any methods that deal with MenuElements should have any special processing attributed to JSeperator removed.
ACTUAL -
The MenuElement interface is not implemented by JSeperator.

---------- BEGIN SOURCE ----------
import java.awt.*;
import javax.swing.*;

public class Sample {
public static void main(String[] args) {
JMenu menu = new JMenu("File");
menu.add(new JMenuItem("Open"));
menu.add(new JSeparator());
menu.add(new JMenuItem("Quit"));

System.out.println("Components:");
Component[] comps = menu.getMenuComponents();
for (int i=0; i<comps.length; i++)
System.out.println(comps[i].getClass().getName());

System.out.println("\nMenuElements:");
MenuElement[] elements = menu.getSubElements();
elements = elements[0].getSubElements();
for (int i=0; i<elements.length; i++) {
MenuElement e = elements[i];
System.out.println(e.getClass().getName());
}

System.out.println(
"\nThe JSeparator wasn't reported in the second query " +
"because JSeparator doesn't implement the MenuElement interface);
}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Menu's getMenuComponents() will report non-MenuElements that are contained within the menu.
