   - [ ] 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: 3.1.4
   * Operating System version: mac os
   * Java version: 1.8
   
   ### Steps to reproduce this issue
   
   1. 在使用 dubbo 3.x 的时候，如果设置了 类似 `System.setProperty("dubbo.service.version", 
"TEST");` 的系统属性，那么就会覆盖(因为dubbo 
只能中引入了属性覆盖机制)`org.apache.dubbo.metadata.MetadataService` 的版本，如下图：

   默认版本是1.0.0
   
   2. 那么在进行MetadataService服务调用的时候就会找不到1.0.0 
的版本，导致出错。出错代码在`org.apache.dubbo.remoting.transport.CodecSupport#checkSerialization`
 中
   
   我想到的解决方案，在进行服务版本的覆写的时候，跳过 MetadataService 服务。如果 MetadataService 
的本版被修改了，如果后续对MetadataService进行一版本的升级，可能存在问题。
