>             Project: Aries
>          Issue Type: Bug
>          Components: JPA
>    Affects Versions: jpa-container-1.0.2, jpa-container-context-1.0.4
>            Reporter: Christian Schneider
>            Assignee: Christian Schneider
>            Priority: Critical

> I have created a small example that shows the problem:
> https://github.com/cschneider/Karaf-Tutorial/tree/master/tasklist-cdi
> The project uses hibernate 4.3, aries jpa and derby. 
> In persistence I work with container managed persistence provided by aries jpa.
> In persistence-emf I directly use the EntiryManagerFactory.
> In both cases I open a JTA transaction, then persist an entity. After a sleep I commit the transaction.
> In a separate thread I look for the number of entities. I would expect this number to be 0 until the transaction is committed. Unfortunately the persist is already shown while the transaction is still open.
> As it also happens with pure EMF the problem is maybe not in aries jpa directly as it is only quite thin then. Still I have no clue what might go wrong.
