   - [ ] 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：
