Any steps to reproduce? Thanks.

To reproduce the error:
Create a project with the following interface:

package JoXer.Menus;

import JoXer.ProgressIndicator.TellUser;

/** Copyright 2003-2007 YAR Anner Ltd.
* 46, Jerusalem St. Kfar-Saba, Israel
*/
/** @version 1.2.2 */

/** Interface requirement for Java-written menu action classes
 *
 * @author  Amotz Anner
 */
public interface MenuActionClass {

    /** Perform the menu action
	 * @return <b>true</b> if action succeeded
	 * @param componentName The name of the component invoking the action.
	 * @param fetcher A context fetcher object.
	 * @param label Label attribute value from the menu item definition. 
     * @param tellUser User teller object. May be <b>null</b>.
     * @param params Optional additional parameters. */
    boolean performAction(MenuFetchContext fetcher, String label, String componentName, TellUser tellUser, Object...params);

}

Invent any definitions for MenuFetchContext and TellUser. They are not important.

Try refactor->change method signature to add the following paramter:

CountDownLatchWithProgress.CountDownable cntDn

As the fourth parameter, before the var-args one. To do that you need to define it as fifth parameter, and then move it
up to fourth position. The index ordinal error seems related to this movement, as it was 4 for this example.

I'm not sure that actual usages are required, but you may add some usage instances to the project, for verisimilitude.

I shall also attach the log for this error.
