             Summary: JPACacheStore should be able to lookup a container manager Persistence Unit
                 Key: ISPN-5549
                 URL: https://issues.jboss.org/browse/ISPN-5549
             Project: Infinispan
          Issue Type: Feature Request
          Components: Loaders and Stores
            Reporter: Sanne Grinovero


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
