[cdi-dev] [JBoss JIRA] (CDI-388) Session bean specialization example is not valid

Martin Kouba created CDI-388: -------------------------------- Summary: Session bean specialization example is not valid Key: CDI-388 URL: https://issues.jboss.org/browse/CDI-388 Project: CDI Specification Issues Issue Type: Bug Reporter: Martin Kouba {code} @Stateless public class LoginActionBean implements LoginAction { ... } @Stateless @Mock @Specializes public class MockLoginActionBean extends LoginActionBean { ... } {code} {{LoginAction}} is a local interface (whether it's annotated with {{@Local}} or not) therefore the bean types of {{LoginActionBean}} are {{LoginAction}}, {{Object}}. On the other hand {{MockLoginActionBean}} does not have a local interface (client views exposed by a particular session bean are not inherited by a subclass; see also the EJB spec 4.9.2.1 Session Bean Superclasses). Therefore the bean types of {{MockLoginActionBean}} are {{MockLoginActionBean}}, {{LoginActionBean}} and {{Object}} (3.2.2 Bean types of a session bean: "the unrestricted set of bean types contains the bean class and all superclasses"). The spec also states (4.3.1 Direct and indirect specialization): {quote} Furthermore, X must have all the bean types of Y. If X does not have some bean type of Y, the container automatically detects the problem and treats it as a definition error. {quote} So I believe the aforementioned example should result in a definition exception. To make it valid the {{MockLoginActionBean}} should also implement {{LoginAction}}. -- This message is automatically generated by JIRA.
