陷入“java.util.ConcurrentModificationException”

// eventList is a LinkedList

public void run() {

    Iterator<Event> it = eventList.iterator();
    int size = eventList.size();

    while(size > 0) {
        while(it.hasNext()) {
            Event e = it.next(); //flaged line

            if(e.ready()) {
                System.out.println(e);
                e.action();
                eventList.remove(e);
                --size;
            }
        }
    }
}

错误的java.util.ConcurrentModificationException在标记的行中抛出(Event e = it.next();).你是否在我的代码中看到一个错误,这个错误明显是抛出异常的原因？
