> Key: ARIES-1393
> URL: https://issues.apache.org/jira/browse/ARIES-1393
> Project: Aries
> Issue Type: Bug
> Components: JPA
> Affects Versions: jpa-2.2.0
> Environment: jpa.support-2.2.0-SNAPSHOT
> eclipselink 2.5.2.
> Reporter: Matthew Pitts
> Assignee: Christian Schneider
>
> When calling txExpr methods with TransactionType.Supports on OSGi-exposed
> JpaTemplate services within a JTA-based setup a TransactionRequired [1]
> exception is thrown when no existing transaction is present.
> The logic in XAJpaTemplate#txExpr is calling EntityManager#joinTransaction()
> regardless of whether there is a current global transaction. So for
> situations where users want to 'support' running within an existing global
> transaction, but not create a new one if one doesn't exist,
> em.joinTransaction() is still being called which results in the exception.
> [1] Caused by: javax.persistence.TransactionRequiredException:
> Exception Description: No externally managed transaction is currently active
