[JBoss JIRA] Created: (WELD-930) Producer is made an alternative if the declaring bean class is an alternative

by Alexey Kazakov (JIRA)

Producer is made an alternative if the declaring bean class is an alternative ----------------------------------------------------------------------------- Key: WELD-930 URL: https://issues.jboss.org/browse/WELD-930 Project: Weld Issue Type: Bug Components: Producers (Methods, Fields and Disposers) Affects Versions: 1.1.0.Final Reporter: Alexey Kazakov I'm looking at examples from https://github.com/pmuir/jboss-as-developer-guide/tree/master/quickstarts There is org.jboss.as.quickstarts.login.EJBUserManager: {code:title=org.jboss.as.quickstarts.login.EJBUserManager|borderStyle=solid} ... @Named("userManager") @RequestScoped @Alternative @Stateful public class EJBUserManager implements UserManager { ... @Produces @Named @RequestScoped public List<User> getUsers() throws Exception { ... } ... } {code} And there is also another bean org.jboss.as.quickstarts.login.ManagedBeanUserManager: {code:title=org.jboss.as.quickstarts.login.ManagedBeanUserManager|borderStyle=solid} ... @Named("userManager") @RequestScoped public class ManagedBeanUserManager implements UserManager { @SuppressWarnings("unchecked") @Produces @Named @RequestScoped public List<User> getUsers() throws Exception { ... } ... } {code} This code works in Weld even if EJBUserManager.getUsers() is not annotated @Alternative. But regarding the spec such a method has an ambiguous EL name "users": {quote} 5.3.1. Ambiguous EL names An ambiguous EL name exists in an EL expression when an EL name resolves to multiple beans. When an ambiguous EL name exists, the container attempts to resolve the ambiguity. If any of the beans are alternatives, the container eliminates all beans that are not alternatives, *except for producer methods and fields of beans that are alternatives*. If there is exactly one bean remaining, the container will select this bean, and the ambiguous EL name is called resolvable. {quote} There is a comment from Pete Muir: {quote} This looks to me like a bug in Weld (one that crept in from a pre-final spec revision) - that it checks if the declaring bean class is an alternative, and if it is, makes the producer an alternative. Can you file a WELD issue for this? I'll update the quickstart to explicitly make the producer an alternative. Pete {quote} -- This message is automatically generated by JIRA.

[JBoss JIRA] (WELD-1094) BeanManager#createInjectionTarget - IllegalArgumentException not thrown if there is a definition error associated with any injection point

[JBoss JIRA] (WELD-991) Incorrect check of bean type when obtaining contextual reference via BeanManager#getReference()

by Martin Kouba (Created) (JIRA)

Incorrect check of bean type when obtaining contextual reference via BeanManager#getReference() ----------------------------------------------------------------------------------------------- Key: WELD-991 URL: https://issues.jboss.org/browse/WELD-991 Project: Weld Issue Type: Bug Affects Versions: 1.1.2.Final Reporter: Martin Kouba CDI 1.0 section "11.3.1 Obtaining a contextual reference for a bean" states: "If the given type is not a bean type of the given bean, an IllegalArgumentException is thrown." However no such exception is thrown. Refer to CDI TCK test [1]. After inspecting the source code I suppose the problem is probably related to following part of *org.jboss.weld.manager.BeanManagerImpl.getReference(Bean<?>, Type, CreationalContext<?>)*: {code} if (!Reflections.isAssignableFrom(bean.getTypes(), beanType)) { throw new IllegalArgumentException(SPECIFIED_TYPE_NOT_BEAN_TYPE, beanType, bean ); } {code} All beans have the bean type *java.lang.Object* (2.2. Bean types) - since java.lang.Object is assignable from any class *Reflections.isAssignableFrom(bean.getTypes(), beanType)* will always return true.

[JBoss JIRA] (WELD-1103) EJB using CMT demarcation with an injection point of type UserTransaction is not detected as definition error

Additional built-in beans* states: "If a Java EE component class has an injection point of type UserTransaction and qualifier @Default, and may not validly make use of the JTA UserTransaction according to the Java EE platform specification, the container automatically detects the problem and treats it as a definition error." ... and EJB 3.1 spec states: *13.3.4 Enterprise Beans Using Container-Managed Transaction Demarcation* "The enterprise bean's business methods, message listener methods, business method interceptor meth- ods, lifecycle callback interceptor methods, or timeout callback methods must not attempt to obtain or use the javax.transaction.UserTransaction interface. ..." *16.12 UserTransaction Interface* "The container must make the UserTransaction interface available to the enterprise beans that are allowed to use this interface (only session and message-driven beans with bean-managed transaction demarcation are allowed to use this interface) either through injection using the Resource annotation or in JNDI under the name java:comp/UserTransaction, in addition to through the EJBContext interface. ..." -- This message is automatically generated by JIRA.

[JBoss JIRA] (WELD-992) Event of type ProcessObserverMethod not fired while adding observer method via AfterBeanDiscovery

by Martin Kouba (Created) (JIRA)

Event of type ProcessObserverMethod not fired while adding observer method via AfterBeanDiscovery ------------------------------------------------------------------------------------------------- Key: WELD-992 URL: https://issues.jboss.org/browse/WELD-992 Project: Weld Issue Type: Bug Components: Bootstrap and Metamodel API, Events Affects Versions: 1.1.2.Final Reporter: Martin Kouba CDI 1.0 *11.5.2.
