initialize Unable to obtain CGLib fast class and/or method implementation for class : cannot be cast to net.sf.cglib.reflect.FastClass

Question

I used Jfinal MVC for site build.

In testController Action, I add call to another static method which involed Spring&Hibernate&Esper Services.

Meet cast exceptions,not sure where is the problem happen. Actually the static method can start successfully when it called in JavaAPP Main but not in TestController.action().
