请描述您的问题

public class JSONObject extends LinkedHashMap implements InvocationHandler

如题，fastjson2相较于v1版本移除了LinkedHashMap泛型，在原项目升级v2版本后出现多处以下告警，经翻阅issues了解到是为了修复 #110，目前暂时用@SuppressWarnings("unchecked")抑制了告警，想请问下后续会考虑将泛型加回来吗？关联问题 #165。

Unchecked assignment: 'com.alibaba.fastjson2.JSONObject' to 'java.util.Map<java.lang.String,java.lang.Object>

public void test1(JSONObject param1){ }
public void test1(Map<String,String> param1){ }

在2.0.3的版本这样的写法是有问题的.

为什么要去掉父类的泛型？
