运行以下代码时我遇到了ConcurrentModificationException（这是实际循环的片段）
我尝试按照此问题Concurrent Modification exception的答案，但发现当我尝试拆分nextLine时会出现重新发送问题。
是否有正确的方法在循环中进行拆分而不会导致异常？
ArrayList<Task> temp = new ArrayList<>();
ListIterator<String> iterator = taskFileFromJob.listIterator();
int count = 0;
while (iterator.hasNext()) {
String nextLine = iterator.next();
if (nextLine != null && nextLine.split(Pattern.quote("|")) != null) {
String[] lineSplit = nextLine.split(Pattern.quote("|"));
temp.add(new Task(lineSplit[0]));
if (lineSplit.length > 1) {
temp.get(count).setDependenciesList(new ArrayList<>(Arrays.asList(lineSplit[1].split(","))));
if (lineSplit.length > 2) {
temp.get(count).setDocumentList(new ArrayList<>(Arrays.asList(lineSplit[2].split(","))));
}
}
count++;
}
}
编辑：这是完整的堆栈跟踪

编辑2：
似乎使用Thread来迭代这是另一个可能的问题。我尝试在包含此块的方法中使用syncronized，但我仍然遇到了同样的问题。
然后我删除了附加线程的使用并最终得到了相同的异常，但堆栈跟踪不同：
