[GitHub] [dubbo] nosixtools opened a new issue #8288: 自研注册中心 Registry 启动报错 2.7.9 提示无扩展 2.7.12 报空指针
nosixtools opened a new issue #8288:
URL: https://github.com/apache/dubbo/issues/8288
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 2.7.12
* Operating System version:
* Java version: 1.8
### Steps to reproduce this issue
1. 使用自定义的注册中心 只实现了 RegistryFactory扩展 ，未实现ServiceDiscovery的扩展
2. 使用 2.7.9版本的dubbo,提示没有ServiceDiscovery的扩展
3. 升级到2.7.12版本的dubbo, 代码启动报错，ServiceDiscovery提示空指针
