JSON文件stream api反序列化出错?报错

按照官方例子，采用如下的写法：

序列化：

JSONWriter writer = new JSONWriter(new FileWriter("/tmp/huge.json"));
writer.startArray();
for (int i = 0; i < 1000 * 1000; ++i) {
      writer.writeObject(new VO());
}
writer.endArray();
writer.close();

反序列化：

JSONReader reader = new JSONReader(new FileReader("/tmp/huge.json"));
reader.startArray();
while(reader.hasNext()) {
      VO vo = reader.readObject(VO.class);
      // handle vo ...
}
reader.endArray();
reader.close();
