[cdi-dev] Clarification on 4.3 Specialization

I have an application containing two wars. testDiffBDA.war testDiffBDA.war/WEB-INF/classes/test/diff/web/FrontEndServlet.class @Inject CounterProducerConsumerModified2 bean; beans-xml-modified2.jar containing one bean and an empty-ish beans.xml : @Inject@CounterModifiedQualifier String modifiedProducer; beans-xml-modified.jar.jar CounterModifiedQualifier (the interface) CounterProducerModified (the bean implementing that interface) AlternativeCounterProducerModified (an alternative specialized bean) beans.xml <alternatives> <class>com.ibm.jcdi.test.beansxml.AlternativeCounterProducerModified</class> </alternatives> My application failed deployment with the error on Weld but worked on OpenWebBeans [ERROR ] CWWKZ0004E: An exception occurred while starting the application testDiffBDA. The exception message was: com.ibm.ws.container.service.state.StateChangeException: org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type String with qualifiers @CounterModifiedQualifier at injection point [BackedAnnotatedField] @Inject @CounterModifiedQualifier com.ibm.jcdi.test.beansxml.CounterProducerConsumerModified2.modifiedProducer at com.ibm.jcdi.test.beansxml.CounterProducerConsumerModified2.modifiedProducer(CounterProducerConsumerModified2.java:0) -- After further investigation and talking to Martin from Weld, the error was caused due to the fact of AlternativeCounterProducerModified disabling the CounterProducerModified bean but itself is not enabled in the jar of beans-xml-modified2.jar. Therefore, no producer is active to produce a bean with the qualifier CounterModifiedQualifier. second bean regardless whether itself is active or not. My understanding is that the specialized should only take effect if itself is enabled. Otherwise, we run into the situation of where the specialized bean is not enabled but it disabled another bean. To me, it is wrong. I also checked the spec: @Alternative @Specializes public class MockAsynchronousService extends AsynchronousService { ... } When an enabled bean, as defined in Section 5.1.2, “Enabled and disabled beans”, specializes a second bean, we can be certain that the second bean is never instantiated or called by the container. Even if the second bean defines a producer or observer method, the method will never be called. The spec says only an enabled bean can specialize a second bean. I would like to know what other people think. Thanks Emily ================= Emily Jiang ejiang(a)apache.org
