abstract classes with @EJB annotation included in libraries will cause deployment failures ------------------------------------------------------------------------------------------ Key: WFLY-11870 URL: https://issues.jboss.org/browse/WFLY-11870 Project: WildFly Issue Type: Bug Components: EJB, Server Reporter: Wolf-Dieter Fink Assignee: Tomas Hofman Priority: Major Labels: Regression, deployment, injection Attachments: ReproducerInjection.zip If an archive include libraries with interfaces and abstract classes the deployment will fail if there are annotations for injection like @EJB. Only if the injected EJB is available within the deployed file (or any other deployment) it is possible to deploy it. As the abstract class can not cause any instance the failure does not make sense. Also former versions are deploying the same file correct and work fine.
