HibernateExtendedBeanManager (Hibernate JavaDocs)

java.lang.Object
- org.jboss.as.jpa.hibernate5.HibernateExtendedBeanManager

All Implemented Interfaces:

ExtendedBeanManager
```
public class HibernateExtendedBeanManager
extends java.lang.Object
implements ExtendedBeanManager
```
HibernateExtendedBeanManager helps defer the registering of entity listeners, with the CDI BeanManager until after the persistence unit is available for lookup by CDI bean(s). This solves the WFLY-2387 issue of JPA entity listeners referencing the CDI bean, when the bean cycles back to the persistence unit, or a different persistence unit.

- Method Detail
  - registerLifecycleListener
```
public void registerLifecycleListener(ExtendedBeanManager.LifecycleListener lifecycleListener)
```
    Hibernate calls registerLifecycleListener to register N callbacks to be notified when the CDI BeanManager can safely be used. The CDI BeanManager can safely be used when the CDI AfterDeploymentValidation event is reached.
    
    Specified by:
    
    registerLifecycleListener in interface ExtendedBeanManager
    
    Parameters:
    
    lifecycleListener - Note: Caller (BeanManagerAfterDeploymentValidation) is expected to synchronize calls to registerLifecycleListener() + beanManagerIsAvailableForUse(), which protects HibernateExtendedBeanManager.lifecycleListeners from being read/written from multiple concurrent threads. There are many writer threads (one per deployed persistence unit) and one reader/writer thread expected to be triggered by one AfterDeploymentValidation event per deployment.
