Answer 1

I wanted to create an application context that works well for both Hibernate 4 and Hibernate 5 at the same time.^[why?]

So I replaced Hibernate-specific transaction manager (org.springframework.orm.hibernate4.HibernateTransactionManager) with Spring JPA transaction manager (org.springframework.orm.jpa.JpaTransactionManager):

// part of my Java Config
@Bean
@Autowired
public JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory, DataSource mainDataSource) {
    final JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory);
    transactionManager.setDataSource(mainDataSource);
    return transactionManager;
}

^[why?] Because this context is shared between different modules that depend on different Spring and Hibernate versions.
