                 URL: https://jira.jboss.org/browse/JBAS-8345
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Weld/CDI
    Affects Versions: 6.0.0.M4
         Environment: Linux 32bit, Java 6
            Reporter: Lincoln Baxter III
            Assignee: Marius Bogoevici
         Attachments: ejb-inject-test.tar.gz

See attached Maven Arquillian Test Project:

Test and results also pasted below.

Workaround in UserService: Changing the @Inject FeedService fs; annotation =
to @EJB FeedService fs; causes injection to occur, but not through CDI.

Thanks.
