I'm not following what this jira is trying to accomplish exactly. The WildFly JPA container implements the JPA contracts for extended persistence contexts using the JPA EntityManagerFactory API and EJB session bean tracking logic for other parts that Hibernate probably doesn't care about.

Is this jira specific to a extended persistence contexts? Or does this jira also apply to application scoped persistence contexts which are very similar to extended persistence context? Application scoped persistence contexts also survive the transaction end.

There are also unsynchronized transaction scoped persistence contexts that may also survive the JTA transaction end, if they are not explicitly joined.
