json里有两个相似的key，成员变量只有其一，json转对象会出现问题[QUESTION]

### 请描述您的问题
*询问有关本项目的使用和其他方面的相关问题。*
class A{
add_time;
}
JSON:{"addtime":xxxxxxx,"add_time":xxxxxxxx},
转换的时候 总会把addtime的值给class A，
但是class A {
addtime;
add_time;
}
就会正常 会把addtime给A的addtime，release最新，
我用源码试了一下 没有这个问题，从maven拉下来的 会出现上述问题

Reproduce the reported conversion with class A and the JSON containing both addtime and add_time, comparing the Maven artifact with the source release mentioned in the issue. Identify the relevant deserialization entry point and add_time handling, then verify whether the packaged and source versions behave differently. Done means the behavior is explained and a regression test covers the confirmed result.
