Sami Korhonen commented on MYFACES-3940:
----------------------------------------
I don't think CDI guarantees that referenced beans are valid. How would
container determinate in which order beans should be removed, if they are e.g.
crossreferencing each other or they are in same scope? If I'm not mistaken,
@PreDestroy is used to release resource that current bean owns, not resources
that are owned by another bean.
However @Singleton bean might just work, if it is referenced both by
@ApplicationScoped bean and @Session bean. This is because singleton is not a
proxy, but a direct reference. Just be sure to set reference from session bean
as transient - otheriwse it will get serialized. Container should reinject
bean, if it's working correctly
