> function getPageClassList from class ConfigService
> has an incorrect signature
> public List<? extends Page> getPageClassList();
> while it should be
> public List<Class<? extends Page>> getPageClassList();
> This function when used causes sometimes ClassCastException. However this is not repeatable. I assume that javac compiler generates code which try to cast to incorrect generic type.
> Loop construction like
> for(Class<? extends Page> clazz : configService.getPageClassList()) {...} is rejected by java compiler
> Please correct the signature in ConfigService and its implementation in XmlConfigService
