What happened to the Annotations (org.jboss.ejb3.annotation) Cache and SerializedConcurrentAccess? Do they not exist anymore or were they renamed/replaced?
@Cache is not supported in AS 7.0 Final. It'll come at a later date.
@SerializedConcurrentAccess will no longer be supported, because EJB 3.1 mandates serialized acces (EJB 3.1 FR 4.3.14).
You can get back the old behavior by specifying @AccessTimeout(0).
