Bug 165676 [JFace] Add javadoc to Window.close() to tell that no shellClosed event is sent

	 * <code>true</code>, which will allow the
	 * <code>handleShellCloseEvent</code> method to be called. Subclasses may
	 * extend or reimplement.
	 * </p>
	 * 
	 * @return whether the window should handle the close event.
