<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> - [x] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.2.0 * Operating System version: Windows 10 / Linux ( Both ) * Java version: 17.0.6 ### Steps to reproduce this issue 我们的应用中存在如下代码： Consider the following code: ```java public interface Person extends Serializable { String getName(); } @Getter @Setter public class Student implements Person { String name; } @Getter @Setter public class Teacher implements Person { String name; } public interface RemoteService { /** return an instance of Student or Teacher */ Person findById(Long id); } ``` 我们想要通过 Dubbo 远程加载一个 `Person` 实例对象（ 注意 Person 只是一个接口，它有两个实现类：`Student` 和 `Teacher`）。 当使用 `tri + hessian2` 时，一切正常。当使用 `tri + fastjson2` 时，应用抛出异常。 We want to remotely load a `Person` instance object through Dubbo (note that Person is just an interface, and it has two implementation classes: `Student` and `Teacher`). When using `tri + hessian2`, it works. When using `tri + fastjson2`, the application throws the following exception. ### Expected Behavior 使用 `tri + fastjson2` 时，如果返回值声明为 父类/接口，都应该能够正确返回。 When using `tri + fastjson2`, if the return value is declared as a parent class/interface, it should be able to return correctly. ### Actual Behavior ``` org.apache.dubbo.rpc.StatusRpcException: INTERNAL : Deserialize response failed at
