> The current {{JpaStore}} implementation starts all its {{EntityManagerFactory}} instances by using the Java SE recommended method, but this has several limitations:
>  - it's likely a duplicated persistence unit as the container will start one as well
>  - duplication leads to name clashes and lack of statistics in dashboards
>  - the container won't inject special features, such as the appropriate JTA context
>  - custom extensions from the container, like on WildFly you get a better scanner
>  - better integration with datasources
>  - Infinispan does a poor job in managing the lifecycle of its custom starte PU (not shutting it down)
>  - several containers apply some customizations to get Hibernate to work best (or at all) on them, you'd bypassing these compatibility fixes
