Cannot construct net.sourceforge.cruisecontrol.BuildLoopInformation

最近在linux上安装了CruiseControl后，启动结果一直报如下错误：

2012-04-13 23:29:36.893::WARN:  /dashboard/buildloop/listener

求助google也没找到好的解决方案，同样版本的CuriseControl在windows下运行正常，在linux下却一直报错。比对windows和linux下的环境，发现linux装的jdk7,而windows装的是jdk6，为此在windows下装了jdk7，此时启动CruiseControl，发现会报上面一样的错误，惊喜，马上把linux下的jdk7换成jdk6，启动CruiseControl，运行正常。

上述错误可以通过加上参数-postenabled false来解决如：
cruisecontrol -postenabled false
-postenabled [true|false]  指定是否要build loop发布builds information到dashboard。默认为true。
