Please expose Hibernate's org.hibernate.cfg.Configuration object in the newly added org.springframework.orm.hibernate4.LocalSessionFactoryBean class.
Previous version org.springframework.orm.hibernate3.LocalSessionFactoryBean clearly does it through its #getConfiguration method. Today LocalSessionFactoryBuilder (i.e. Spring's extension of Hibernate's Configuration class) is only a local variable in the #afterPropertiesSet method.
This is actually a very important piece of functionality for us.
