3.1.3版本QuartzPlugin问题

[Covenanter]

我使用的maven版本，使用3.1.2的QuartzPlugin时候，代码中加入如下：
QuartzPlugin quartzPlugin = new QuartzPlugin("job.properties");
me.add(quartzPlugin);
出现异常信息

换成3.1.3版本，继续跑出现以下异常：

java.util.regex.PatternSyntaxException: Unexpected internal error near index 1

不懂3.1.3版本的ClassSearcher有更改什么。
最后我按照八皮的http://my.oschina.net/b1412/blog/68082
重写了QuartzPlugin，使用3.1.2版本可以正常运行起来，希望作者能够维护一下
