Exception in thread "HouseKeeper" java.lang.NullPointerException at org.logicalcobwebs.proxool.HouseKeeperController.getHouseKeeperToRun(HouseKeeperController.java:53)

我是严格按照要求来操作的；
1，先把ｊｅｅｂｂｓ复制到webapps目录下；
2，启动tomcat,
3，安装；
4，再重新启动时，就发生了楼上的异常，
恳请官方找出补救办法！谢谢了。
另：我用的jdk,tomcat,mysql,都是在本网站上下载的。所以应该不是版本的问题。
到底是不是程序的bug?

据群里的同学反应，有好几人出现了类似的异常。
看来，不是我一人的问题了。
