[jboss-jira] [JBoss JIRA] (WFLY-6485) add JPA dependency in subdeployments to avoid NPE
[
https://issues.jboss.org/browse/WFLY-6485?page=com.atlassian.jira.plugin....
]
Scott Marlow updated WFLY-6485:
-------------------------------
Description:
WeldDeploymentProcessor only processes top level deployments (jpa dependencies for
subdeployments are skipped). This means that subdeployments that CDI inject a persistence
unit/context, will not add a dependency on the JPA PersistenceUnitService. As a result,
the PersistenceUnitService is referenced before it is started (which leads to
PersistenceUnitService.entityManagerFactory being null).
We should avoid the following NPE by ensuring that dependencies on the JPA persistence
unit are added for all sub-deployments.
