- [ ] 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: 2.7.18
* Operating System version: macos
* Java version: 1.8

### Steps to reproduce this issue

1. 服务端采用dubbo泛化实现方式，服务端直接返回map类型的响应对象，响应对象中有list集合，list中返回的数据为map结构
2. 客户端正常调用，收到的响应数据list中的map结构没有转换为接口定义的实际java对象，导致程序做进一步处理报错
3. 经验证3.1.1 版本仍然存在该问题
4. 经排查后出问题的类为DecodeableRpcResult，代码段如下：

### Expected Behavior

consumer端能正常反序列化

### Actual Behavior
consumer 端对于响应参数字段中List 字段的泛型处理错误
