jdk1.7.0_71迭代器bug

做java开发这么多年，终于逮住了一个jdk版本的bug。如下代码所示，jdk1.7.0_71这个版本会报下面错误，jdk1.7.0_80就可以正常运行了。具体原因不做具体说明。

private List<Long> filterRxIdsHasProblem(List<Long> oriList, List<Long> lastlist) {
        int size = lastlist.size();
        Iterator<Long> ori = oriList.iterator();
        Iterator<Long> last = lastlist.iterator();
        int i = 0;
        while (ori.hasNext()) {
            logger.info("ori->last->list:{},last:{}", JsonUtil.toJSONString(oriList), JsonUtil.toJSONString(lastlist));
            if (i == size) {
                break;
            }
            Long oriLong = ori.next();
            while (last.hasNext()) {
                Long it = last.next();
                if (oriLong.equals(it)) {
                    logger.info("ori->last->list-1:{},last:{}", JsonUtil.toJSONString(oriList), JsonUtil.toJSONString(lastlist));
                    last.remove();
                    ori.remove();
                    break;
                }
            }
            i++;
            continue;
        }
        return oriList;
    }
