   是有点别扭，但官方文档https://docs.oracle.com/javase/8/docs/platform/serialization/spec/output.html#a5324 并未强调writeReplace的返回值需实现序列化接口，事实上SerializationProxy是否实现序列化接口也并不影响com.alibaba.com.caucho.hessian.io.JavaSerializer的逻辑
   java原生的ObjectOutputStream与ObjectInputStream也可正常运行
   ```
   @Test
       public void testObjectSerialization() throws IOException, ClassNotFoundException {
           // given
           ByteArrayOutputStream baos = new ByteArrayOutputStream();
           ObjectOutputStream oos = new ObjectOutputStream(baos);
           ObjectId objectId = new ObjectId("5f8f4fcf27516f05e7eae5be");
   
           // when
           oos.writeObject(objectId);
   
           // then
           assertTrue(new String(baos.toByteArray()).contains("org.bson.types.ObjectId$SerializationProxy"));
           assertArrayEquals(new byte[] {-84, -19, 0, 5, 115, 114, 0, 42, 111, 114, 103, 46, 98, 115, 111, 110, 46, 116, 121, 112, 101, 115,
                           46, 79, 98, 106, 101, 99, 116, 73, 100, 36, 83, 101, 114, 105, 97, 108, 105, 122, 97, 116, 105, 111, 110, 80, 114,
                           111, 120, 121, 0, 0, 0, 0, 0, 0, 0, 1, 2, 0, 1, 91, 0, 5, 98, 121, 116, 101, 115, 116, 0, 2, 91, 66, 120, 112, 117,
                           114, 0, 2, 91, 66, -84, -13, 23, -8, 6, 8, 84, -32, 2, 0, 0, 120, 112, 0, 0, 0, 12, 95, -113, 79, -49, 39, 81, 111,
                           5, -25, -22, -27, -66},
                   baos.toByteArray());
   
           // when
           ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
           ObjectInputStream ois = new ObjectInputStream(bais);
           ObjectId deserializedObjectId = (ObjectId) ois.readObject();
   
           // then
           assertEquals(objectId, deserializedObjectId);
       }
   ```
