resolvido [Dúvida] ConcurrentModificationException

[zAth]

Estou tendo esse erro, já tinha tido esse erro antes e eu comecei usando iterator, daquela vez resultou..

Agora usei iterator novamente para tentar arrumar esse erro, mas continuo obtendo o erro.

 

Código:

 

 

    static ArrayList<Cooldown> toRemove = new ArrayList<>();
    static ArrayList<Cooldown> cooldowns = new ArrayList<>();    

    static void start() {
        getServer().getScheduler().scheduleSyncRepeatingTask(this, () -> {

            checkExpireds();

            remove();

        }, 20, 600 * 20);
    }

    static void checkExpireds() {
        Iterator<Cooldown> iterator = cooldowns.iterator();
        while (iterator.hasNext()) {

            Cooldown cooldown = iterator.next();

            if (cooldown.getExpireDate() <= System.currentTimeMillis()){
                cooldowns.remove(cooldown);
                toRemove.add(cooldown);
            }

            iterator.remove();
        }
    }

    static void remove() {
        Iterator<Cooldown> iterator = toRemove.iterator();
        while (iterator.hasNext()) {
            Cooldown cooldown = iterator.next();

            getConfig().set("Kits." + cooldown.getKit().getName() + ".ActiveCooldowns." + cooldown.getPlayer(), null);
            saveConfig();

            toRemove.remove(cooldown);
            iterator.remove();
        }
    }

( linha 38 e 49: iterator.remove() )

[leonardosc]

Tira isso

 

cooldowns.remove(cooldown);

 

deixa só o 

 

iterator.remove()

 

pq ele já ta removendo do "cooldowns".

 

Faz o mesmo no toRemove, deixa só o iterator.remove()
