--------------------------------
Fix Version/s: 0.1
> Lifecycle issues with PersistenceBundleManager
> ----------------------------------------------
>
> Key: ARIES-137
> URL: https://issues.apache.org/jira/browse/ARIES-137
> Project: Aries
> Issue Type: Bug
> Components: JPA
> Reporter: Alan Keane
> Assignee: Timothy Ward
> Fix For: 0.1
>
>
> EntityManagerFactory only gets registered for a unit if a matching
> PersistenceProvider service
> is bound before the persistence bundle is added to the tracker.
> The PersistenceBundleManager will only attempt to setup an
> EntityManagerFactoryManager
> for the PersistenceProvider services available at the point when a
> persistence bundle
> is first detected and subsequently only tracks the persistence bundles that
> get matched with a Provider.
> Any Persistence bundle added to the tracker before a (suitable)
> PersistenceProvider is
> available will never get matched with a provider.
> The PersistenceBundleManager#addingProvider method should check for
> persistence bundles
> that are not matched with a provider and attempt to resolve.
> One possible solution would be that the addingBundle and setUpManager methods
> use a
> null object style pattern (or similar) for the EntityManagerFactoryManager so
> that
> detected persistence bundles without a matching provider are still tracked.
> When a provider service is then bound to the PersistenceBundleManager via
> addingProvider,
> iterate through all tracked persistence bundles and attempt to match those
> that do
> not have a valid EntityManagerFactoryManager associated.
> (Note: MultiBundleTracker does not expose the bundles tracked, but by
> exposing getBundles()
> for above and also using getObject() where the EntityManagerFactoryManager is
> being returned
> there probably wouldn't be any need for bundleToManagerMap and associated
> synchronization)
> Also I think an ExecutorService should be used for the setUpManager calls
> rather
> than this work being done on a framework event thread.
> (I don't have time right now to look at this properly, so somebody might want
> to have a
> look/take this in the meantime)
