Помогите Не ставится metadata в event`е

PHP:

@EventHandler
    public void onLeash(PlayerLeashEntityEvent event) {

        //Если привязали к забору
        if(event.getLeashHolder().getType().equals(EntityType.LEASH_HITCH) &&
                (
                        event.getEntity().getType().equals(EntityType.HORSE) ||
                        event.getEntity().getType().equals(EntityType.MULE)) ||
                        event.getEntity().getType().equals(EntityType.DONKEY)
                ){

            Location leash = event.getLeashHolder().getLocation();
            Entity horse = event.getEntity();
            String playerName = event.getPlayer().getName();

            leashedHorses.put(
                    playerName,
                    horse
            );
            leashHolderLocations.put(playerName, leash);
//RolePlayHorse главный класс
// класс extends JavaPlugin один
            horse.setMetadata("owner", new FixedMetadataValue(new RolePlayHorse(), playerName)); // тут ошибка
            event.getPlayer().sendMessage("Вы привязали свою лошадь к забору");
    }

ну естественно. какого хрена ты его инициализируешь второй раз. тут должно быть RolePlayHorse.instance или чет такое

 

Один раз в одном классе

 

ты на каждый евент создаешь объект плагина, или по сути второй плагин.
Ядро срется, что запускается плагин, который уже запущен.

Как тебе и сказали

 

Спасибо. Ваше "чет такое" прям таки мне помогло. (нет)
Решил проблему конструктором в классе с ивентом:

PHP:

public LeashEvents(Plugin plugin){
        this.mainClass = plugin;
    }
