* component scanning autodetects the new EE 6 "javax.annotation.ManagedBean" stereotype

* bean properties of type enum array/collection can be populated with comma-separated String
* removed getBeansWithAnnotation(Class,boolean,boolean) method from ListableBeanFactory
* PropertyPlaceholderConfigurer is compatible with Spring 2.5 extensions (again)
