Scott,
Take this for instance: We have the class
*CentralAuthenticationServiceImpl*as a
*final* one. I just turned back this class as it was in the released package
of CAS 3.2.1, and the following exception comes up:
[PORTAL][ERROR] StandardContext.filterStart(3639) | Exception starting
filter Acegi Filter Chain Proxy
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'centralAuthenticationService' defined in ServletContext resource
[/WEB-INF/cas-spring-config/applicationContext.xml]: Initialization of bean
failed; nested exception is
org.springframework.aop.framework.AopConfigException: Could not generate
CGLIB subclass of class [class
org.jasig.cas.CentralAuthenticationServiceImpl]: Common causes of this
problem include using a final class or a non-visible class; nested exception
is java.lang.IllegalArgumentException: Cannot subclass final class class
