### 1. Bug Description
咨询下，spring cloud框架 feign远程调用。 tx-manager 能看到注册上的两个tc，但是exception表里没有任何数据是啥原因？自然也不能回滚，A 代码中 访问B服务.然后手动写死抛出一个RuntimeException的子类，然后B服务数据没回滚可咋整 。 在线等。今天解决不了就得回家烤红薯为生了。

### 2. Environment:
- JDK version: 1.8
- OS: Ubuntu
- TX-LCN version: 5.0.2.RELEASE
- Others:

### 3. Exception Stacktrace

```
Paste your Exception Stacktrace here!
```

### 4. Tour Idea

No source files, tests, or entry points are named. Start by tracing the Feign call flow between services A and B and how tx-manager records exceptions for the described RuntimeException scenario. Reproduce the case on JDK 8, Ubuntu, and TX-LCN 5.0.2.RELEASE; done when the missing exception record and rollback behavior have a confirmed cause.
