constraints attribute doesn't work for menubar

Hello,

specifying constraints attribute for menubar tag doesn't have any affect.
here is the possible fix for the problem. Parser.addChild method
should be modified like this:

      //  Set a JMenuBar for JFrames, JDialogs, etc.
      //
      if (component instanceof JMenuBar) {
        try {
          Method m =3D parent.getClass().getMethod("setJMenuBar", new
Class[]{JMenuBar.class});
          m.invoke(parent, new Object[]{component});
        } catch (NoSuchMethodException e) {
!                       if (constrains =3D=3D null) {
!                               parent.add(component);
!                       }
!                       else {
!                               parent.add(component, constrains);
!                       }
        } catch (Exception e) {
          // intentionally empty
        }
