> Instead of having two different components: "DroolsSpringTransactionManager" and "DroolsSpringJpaManager" that aim to do the work of "org.springframework.orm.jpa.JpaTransactionManager", and trying to fit a JTA model into it, the Spring's "JpaTransactionManager" itself should be used.
> And instead of manually managing and constantly getting references to a "proper entity manager" from JpaManger within a SingleSessionCommandService, a @PersistenceContext should be injected. This will decouple SingleSessionCommandService from JpaManager interface, and will allow _any_ JPA provider to inject an entity manager.
> It has more benefits, such as trust in underline JPA providers ( e.g. Hibernate ) and Spring Transaction Management capabilities to manage the process that they are actually excellent at.
