一个Log4j 1.2.15引起的一个怪异问题

大概在2个月前已经完成了sword项目的源代码开发，并且在eclipse环境中已经完成了功能性测试。但是打包成jar文件进行运行问题，出现下面的问题：Log4jLoggerFactory
的死循环。

。。。。

由于工作项目忙的原因一直没有去研究这个问题。
看到了je的问答上回答说：Log4j 1.2.15存在一个bug会导致log4j:ERROR LogMananger.repositorySelector was null likely due to
于是我换成了Log4j 1.2.14版本，问题解决了！

至于为什么eclipse下为什么运行正常，在单独命令行运行jar时却会有错误还是没有想通。
谁知道能给原因吗？
