behaviour of CDI bean @Specializes session bean is undefined ------------------------------------------------------------ Key: CDI-220 URL: https://issues.jboss.org/browse/CDI-220 Project: CDI Specification Issues Issue Type: Clarification Components: Java EE integration Affects Versions: 1.0, 1.1.EDR Reporter: Mark Struberg Assignee: Antoine Sabot-Durand Labels: CDI_spec_chge, F2F2016 Fix For: 2.0 (discussion) The current spec doesn't define what should happen if a CDI bean @Specializes a session bean, e.g. @Stateless public class Horse {..} @ApplicationScoped @Specializes public class Trakehner extends Horse {..} Section 3.2.4 explicitely forbids the other way around. I think we should also treat the above case as error. Otherwise we would end up getting different results whether we use @Inject or @EJB to inject a Horse.
