I've added try\catch to make sure it is not my code throwing exception.
Also i've tryed adding\removing listener to
getEventDispatcher(). but if exception was thrown - it won't help. As well as creating new listener this way

public void removeAndAddListener() {
    System.out.println("Before removing " + getEventDispatcher().getListeners());
    if (listener == null) {
        getEventDispatcher().removeListener(this);
    } else {
        getEventDispatcher().removeListener(listener);
    }
    listener = null;
    listener = new ChatboxListener() {
        @Override
        public void onMessageReceived(MessageEvent messageEvent) {
            ((MagicArena)Environment.getBot()).onMessageReceived(messageEvent);
        }
    };
    System.out.println("After removing " + getEventDispatcher().getListeners());
    getEventDispatcher().addListener(listener);
    System.out.println("After adding " + getEventDispatcher().getListeners());
}

This bug is very hard to catch cos it happens not often, and bot continue working after throwing this exception until it need to do something after chat message appears. Chatlistener is not working anymore so bot is not working too as expected, but its continue to loop and perform some stupid actions, not as it is supposed to.
This might be a cause of tons of bans.
