Blad plugin na gamemode

Cześć, ostatnio (3 dni temu) zacząłem pisać plugin (pierwszy) na gamemode i mam taki problem bo wyskakuje mi błąd "An internall error"

Cytat

public class GameModeCMD implements CommandExecutor {
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("gamemodee")) {
            if (!(sender.hasPermission("cmd.gamemode"))) {
                sender.sendMessage(ChatColor.RED + "Nie masz uprawnien do tej komendy");
                return true;
            }
            if (args.length == 1) {
                if (args[0].equals(0) || args[0].equalsIgnoreCase("s")) {
                    Player p = (Player) sender;
                    p.setGameMode(GameMode.SURVIVAL);
                    sender.sendMessage(ChatColor.GREEN + "Twoj tryb gry zostal zmieniony na survival");
                    return true;
                }
                if(args[0].equals(1) || args[0].equalsIgnoreCase("c")) {
