InvocationTargetException wodurch?

[Darky^]

Hi!

Ich hab folgenden Code:

    @Override
    public List<String[]> getHeaders(String name, String pass) {
        Benutzer b = em.find(Benutzer.class, name);
        List<String[]> headers = new LinkedList<String[]>();
        List<Nachricht> nachrichten = null;
        if((b!=null) && (b.getPass().equals(encodePass(pass)))){
            nachrichten = b.getNachrichten();
            for(Nachricht n : nachrichten){
                headers.add(new String[]{n.getId().toString(), n.getAbsend(), n.getDatum().toString()});
            }
        }
        return headers;
    }

und erhalt dann eine InvocationTargetException und hab keine Ahnung warum :

Da passt wohl was mit den keys nicht.
