java.io.NotSerializableException: java.util.ArrayList$SubList

一个同事发MQ消息，类似代码如下

List<Integer> list = new ArrayList<Integer>(200);

for (int i = 0; i < 100; i++) {

list.add(i);

}

for (int j = 0; j < 33; j++) {

TestDto t = new TestDto();

t.setList(list.subList(0, 3));

p.send(t);

list.subList(0, 3).clear();

}

if (!list.isEmpty()) {

TestDto t = new TestDto();

t.setList(list);

p.send(t);

}

抛出异常信息：

At some point you're using something like:

x
= myArrayList.subList(a,b));

After this x will not be serializable as the sublist object returned from subList() does not implement it. Try doing

x
= new ArrayList(myArrayList.subList(a,b)));

instead.
