>          Components: EJB
>         Environment: *full* profiles with configured CMP subsystem and added configuration of entity-bean instance pool
>            Reporter: Wolf-Dieter Fink

> If the pool for entity-bean instances is added to the ejb3 subsystem and CMP is used a NullPointerException is thrown if the instances is obtained from the instance-pool. This will be the second access to the entity.
> The problem is that the PersistenceContext is not set correct if the instance is obtained from the pool.
> Caused by: java.lang.NullPointerException
