[jboss-as7-dev] [EE7/JPA 2.1] Question about accessing the CDI BeanManager for a component on AS7 or later...

I would like to give feedback to the JPA 2.1 EG, on the entity listener enhancement to support CDI. If the deployment archive that contains the persistence unit, is a bean archive, the BeanManager needs to be passed in as a property when creating the persistence unit service. The persistence provider will use the BeanManager to create instances of the entity listener classes, do injection and trigger lifecycle methods. Currently, the only way to get the CDI BeanManager in AS7, is doing a "java:comp/BeanManager" lookup (not helpful during deployment) or via the BeanManagerService. I tried to have the PersistenceUnitService depend on the BeanManagerService, but couldn't start the PersistenceUnitService service (got a "org.jboss.msc.service.CircularDependencyException: Service jboss-as has a circular dependency" http://pastie.org/4565684). I'll also need to get access to the BeanManager earlier than the install phase. I need to pass the BeanManager as a property to the PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo, Map) invocation which might occur early (if class transformers will rewrite application classes before they are loaded). I could avoid having the PU service depend on the BeanManagerService if I instead arrange for the PU service to get the BeanManager from the deployment unit (if available). However, if the BeanManagerService is stopped, the pu service wouldn't be stopped if we have a direct reference to the BeanManager. So, this (deployment unit) hack sounds less than ideal. Git branch https://github.com/scottmarlow/jboss-as/tree/seven_jpa2_1_BeanManager integrates with the latest Hibernate master branch (Hibernate needs to be built locally) and has the currently broken BeanManager access code (gets the CircularDependencyException during deployment).
