> @Transaction return NPE on qualified Datasource injections
> ----------------------------------------------------------
>
> Key: DELTASPIKE-508
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-508
> Project: DeltaSpike
> Issue Type: Bug
> Components: JPA-Module
> Affects Versions: 0.5
> Environment: Linux, JBoss-EAP-6.2, Java 7
> Reporter: Cloves J. G. Almeida
> Assignee: Mark Struberg
> Priority: Minor
>
> When using JTA transactions (and probably Resouce Local), a bean injecting a
> qualified DataSource _without an EntityManager also being injected_ will fail
> with an NPE if there's no default EntityManager or won't put the correct
> datasource into the transaction (and fail or act inconsistently).
> The reason is that in
> org.apache.deltaspike.jpa.impl.transaction.TransactionStrategyHelper.resolveEntityManagerQualifiers
> only injected EntityManagers are scanned for qualifiers used to resolve.
> A workaround is to place a qualified EntityManager pointing to the same
> datasource. This is limited, however. Some use cases, like batch processing
> does not require an EntityManager and one might not be available.
