Java serialization keeps a record of every object written to a stream. If the same object is encountered a second time, only a reference to it is written to the stream, and not a second copy of the object; so circular references aren't the problem here.


But serialization is vulnerable to stack overflow for certain kinds of structures; for example, a long linked list with no special writeObject() methods will be serialized by recursively writing each link. If you've got a 100,000 links, you're going to try to use 100,000 stack frames, and quite likely fail with a StackOverflowError.


It's possible to define a writeObject() method for such a list class that, when the first link is serialized, simply walks the list and serializes each link iteratively; this will prevent the default recursive mechanism from being used.

错误原因：被序列化的对象含有嵌套引用
