[GitHub] [incubator-dubbo] Johnson-Jia opened issue #3660: dubbo自定义异常
- [ ] I have searched the [issues](https://github.com/apache/incubator-dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/incubator-dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 2.7.0
* Operating System version: Linux
* Java version: 1.8
### Steps to reproduce this issue
1. 创建两个项目dubbo生产者项目、消费者项目
2. 创建一个自定义异常并继承Exception。
https://github.com/Johnson-Jia/Johnson/blob/master/BaseException.java
https://github.com/Johnson-Jia/Johnson/blob/master/ErrorMsgException.java
3. 生产者内抛出一个 ErrorMsgException 异常，dubbo消费者捕获到一个null异常。（序列化问题？）

找到问题了，我用 2.6.2版本抛出自定义异常后在cglib MethodProxy#invoke 里面抛出的InvocationTargetException 异常,里面只嵌套一层getTargetException() 就可以拿到自定义异常。
用2.7.0 在cglib MethodProxy#invoke 里面抛出的InvocationTargetException 异常，里面只嵌套二层getTargetException() 才能拿到自定义异常。
