> beanFactory.setBeanClassLoader(classLoader);
> /* Where is BeanWrapper created by createBeanInstance& return to client */
> //start watch thread
> fam.start();
> }
> {code}
> this orphaned code contains {{RootBeanDefiniton}} parameter
> {{org.springframework.beans.factory.support.RootBeanDefinition}} mbd
> which is used to construct class of bean here:
> {{Class beanClass = resolveBeanClass(mbd, beanName, null);}}
> i assume createBeanInstance is implemented in possibly 2.4.x?
> Thanks!
