Wrong injection made by container --------------------------------- Key: AS7-6500 URL: https://issues.jboss.org/browse/AS7-6500 Project: Application Server 7 Issue Type: Bug Components: EE, EJB, JPA / Hibernate Affects Versions: 7.1.2.Final (EAP), 7.1.3.Final (EAP), 7.1.4.Final (EAP) Reporter: Luan Cestari Assignee: Scott Marlow Description of problem: I got an issue in a salesforce case [1] about an incorrect injection. [1] https://c.na7.visual.force.com/apex/Case_View?id=500A000000CRqDG&sfdc... Version-Release number of selected component (if applicable): How reproducible: To reproduce the case is required to have two PersistentUnit (PU), a Abstract class with a setter method to inject one PU and others classes inheriting the Abstract class and overriding the setter method to inject a different PU. In the runtime, the container inject twice the PU, first the correct PU and then the PU described in super class. I talked with the client (who is a Red Hat consultant) and we made the attached project based on a very simple JBoss example to reproduce the issue which happens in EAP6. I put a lot of 'println' to be very clear (even printing stacktrace to show who is calling). The most important files are: -> hibernate4Test/src/main/java/org/jboss/as/quickstart/hibernate4/data/BaseDAO.java -- The abstract class with the default PU injection -> hibernate4Test/src/main/java/org/jboss/as/quickstart/hibernate4/data/MemberRepository.java -- BaseDAO subclass -> hibernate4Test/src/main/java/org/jboss/as/quickstart/hibernate4/data/SecondaryMemberRepository.java -- BaseDAO subclass -> hibernate4Test/src/main/java/org/jboss/as/quickstart/hibernate4/data/MemberListProducer.java -- The class which inject the MemberListProducer and SecondaryMemberRepository -> hibernate4Test/src/main/resources/META-INF/persistence.xml -- We changed the configuration here to each PU have a different entity mapped Steps to Reproduce: Actual results: The EM injection occurs twice, which the last one the wrong EM. Expected results: Just one injection occurs. Additional info:
