Thierry Delprat commented on NXP-5782:
--------------------------------------
To summarize the problem : If a Stateful EJB3 has an injected fields
(@Resource) that are transient, reactivation will always fail.
What happends :upon reactivation the container tries to reinject transient
fields but fails in a NPE inside the injection code (bean is null because it is
still in process of beeing reactivated)

This means @Resource fields can not be transient : the problem is that after
reactivation the EJBContext initially injected is no more valid ...
=> This looks to me like a bug (we never had this issue with JBoss 4.x
