[Plugin programing] Nametag ohne fremends Plugin (z.B.: iTag; TagAPI, ProtcolHack) ändern

[Laatzo]

Hallo Leute,

ich bin gerade dabei ein Nick-Plugin zu programmieren, mein Problem ist, dass ich nicht den Nametag (Das ist der Name über dem Kopf) ändern kann.
Ich habe hier man den Code:

[...]
private Player p;
    public NickPlayer(Player p) {
                 this.p = p;
        }

public void setPlayerTagName(String name) {
        EntityHuman eh = ((CraftPlayer)p).getHandle();         
                PacketPlayOutEntityDestroy p29 = new PacketPlayOutEntityDestroy(p.getEntityId());       
                PacketPlayOutNamedEntitySpawn p20 = new PacketPlayOutNamedEntitySpawn(eh);

        try {            
                         Field profileField = p20.getClass().getDeclaredField("b");
                         profileField.setAccessible(true);
                         profileField.set(p20, new GameProfile(p.getUniqueId(), name));
        } catch (Exception e) {
                         e.printStackTrace();
                }   
        for(Player o : Bukkit.getOnlinePlayers()) {
                         if(!o.getName().equals(p.getName())) {
                                   ((CraftPlayer)o).getHandle().playerConnection.sendPacket(p29);
                                   ((CraftPlayer)o).getHandle().playerConnection.sendPacket(p20);
                         }
                 }
}

[...]

Leider kommt ein Fehler, den ich mir nicht erklären kann, da er die UUID nicht setzen kann:

Die Zeile 20 in der Class NickPlayer ist folgende:

[...]
profileField.set(p20, new GameProfile(p.getUniqueId(), name));
[...]

Bei der NickCommand Class in Zeile 27 wird folgendes auf gerufen:

Player p = (Player)sender;
NickPlayer np = new NickPlayer(p);
[...]
String nickname = np.randomNick();
np.setDisplayName(nickname);
np.setPlayerListName(nickname);
np.setPlayerTagName(nickname); // Zeile 27
[...]

Ich hoffe das Mein Problem nachvollziehbar ist
