[jboss-jira] [JBoss JIRA] (WFLY-1322) CDI BeanManager (WeldBeanManagerServiceProcessor) needs to be created during Phase.FIRST_MODULE_USE for applications that have JPA classes that are rewritten/enhanced during deployment

    [ https://issues.jboss.org/browse/WFLY-1322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12774560#comment-12774560 ] 

Scott Marlow commented on WFLY-1322:
------------------------------------

Thanks, I'll avoid the optional dependency.

I would like to add a JPA (PU service) dependency on BeanManagerService (service name building) and WeldDeploymentMarker (detecting presence of beans.xml).  

JPA can't depend directly on the Weld subsystem (would be a cycle).  I probably could have the JPA subsystem depend on org.jboss.as.server.deployment.Attachments instead of WeldDeploymentMarker (could move WeldDeploymentMarker.MARKER there).  For BeanManagerService, I could probably either inline a copy of BeanManagerService.serviceName(du).  

Do you care which way I handle this?  I could also move the JPA subsystem things that Weld depends on, to a different JPA module to avoid the cycle between Weld/JPA.

> The JPA deployment subsystem, needs to pass a (deployment) CDI bean manager instance into the persistence provider, when creating the (container) entity manager factory.  
> If JPA detects that classfile enhancing might be needed for the persistence units classes, the entity manager factory is created during the Phase.FIRST_MODULE_USE phase (so that JPA transformers can be registered before any deployer accesses the deployment classloader).  
> If JPA classfile rewriting is not needed, the entity manager factory is created during the Phase.INSTALL phase.
