请问下，1.46 生成coverage失败，能否帮忙看下 #19

使用的1.46版本 maven配置和报错文件，看问题是没有loaded的类，不知道怎么解决

@xiaoyao-jimmy 一定要用1.46吗？

jmockit的作者更新jmockit速度太快，差不多1-2个月就一个新版本, 向下兼容性也差。一些api说没有了就没有了。

JMockit中文网(jmockit.cn)上的大多数例子是基于1.36这个版本的，如果1.36能满足你的需求，就先用1.36吧，JMockit中文网(jmockit.cn)上关于用JMockit做覆盖率的例子：见 http://www.jmockit.cn/showArticle.htm?channel=3&id=30

（by the way，我最近工作有点忙，还没有去看1.46的jmockit，作者改了些啥。待有空了，再研究一下1.46。）

@hzdavid 136版本 没报错 也没生成覆盖率结果文件

maven-surefire-plugin 2.20 -javaagent:"${settings.localRepository}/org/jmockit/jmockit/1.36/jmockit-1.36.jar=coverage" true -Dcoverage-metrics=all html D:/tmp/codecoverage-output all
