Exception in thread "AWT-EventQueue-0"

[frontier]

Hi, habe ein kleines Programm zu den Türmen von Hanoi ind Java geschrieben, was auch soweit funktioniert. Allerdings kommt sporadisch immer eine Fehlermeldung und ich habe auch noch ein paar Grafikprobleme mit Swing. Evtl. kann mir jemand helfen.

public class Main {

	public static void main(String[] args) {		
		HanoiAlgorithmus hanoi = new HanoiAlgorithmus(10);		
	}

}

import java.util.ArrayList;
import javax.swing.JLabel;

public class HanoiAlgorithmus{
	private int anzahl;
	private HanoiGUI gui;	
	
	public HanoiAlgorithmus(int n){
		anzahl = 0;
		gui = new HanoiGUI(n);
		ArrayList<JLabel> turmA, turmB, turmC;
		turmA = gui.getStab(1);
		turmB = gui.getStab(2);
		turmC = gui.getStab(3);
		hanoiTuerme(n, turmA, turmC, turmB);
	}

	private void hanoiTuerme(int n, ArrayList<JLabel> turmA,ArrayList<JLabel> turmB,ArrayList<JLabel> turmC){
	   if ( n > 1 ) {
                hanoiTuerme(n - 1, turmA, turmC, turmB);                    
                gui.remove(turmA, turmB);                    
                hanoiTuerme(n - 1, turmC, turmB, turmA);
        } else
        		gui.remove(turmA, turmB);
        anzahl++;		
	}
	
    public int getAnzahl(){
        return anzahl;
    }
}

Es kommt beim ausführen folgende Fehlermeldung in der Konsole. Das Programm läuft aber bis zum Ende durch.

Fehler: (Die Zahl hinter "No such child" ist nicht immer 1 sie ist auch mal 4, 0 oder was anderes)
