------------------------------------
Summary: XAJpaTemplate calls EntityManager#joinTransaction
regardless of desired TransactionType
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
When calling txExpr methods with TransactionType.Supports on OSGi-exposed
JpaTemplate services with a JTA 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
