La apariencia no se actualiza en Swing JTabbedPane

Question

He creado una aplicación en Java Swing. Ofrezco la opción de cambiar la apariencia de la aplicación desde un menú, pero después de agregar una nueva pestaña en JTabbedPane , no se actualiza con la nueva apariencia.

Ya he usado este código:

Window windows[] = Frame.getWindows();
for(Window window : windows) {
SwingUtilities.updateComponentTreeUI(window);
}

Aprovechando el ejemplo de @ Andrew y esto viejo, parece funcionar para mí.
