[GitHub] [dubbo] zrlw commented on issue #8681: github构建日志里有很多涉及RegistryProtocol的异常
zrlw commented on issue #8681:

3.0的 org.apache.dubbo.registry.integration.RegistryProtocol.destroy()方法同样存在ApplicationConfig已释放的问题，github构建日志片段内容摘录如下：
（Unit Test On windows-2019 (JDK: 8)完整日志：https://github.com/zrlw/dubbo/runs/3565948379?check_suite_focus=true ）
```

```
PS：
考虑到master分支github日志ReferenceConfigTest测试方法在RegistryProtocol的doOverrideIfNecessary()里获取currentUrl时出现NPE：
```
URL currentUrl = exporter.getInvoker().getUrl();
```
3.0分支的此处获取currentUrl的代码也可能存在出现NPE风险。
