Weld SE container does not properly load extension classes at boot
------------------------------------------------------------------

                 Key: ARQ-335
                 URL: https://jira.jboss.org/browse/ARQ-335
             Project: Arquillian
          Issue Type: Bug
          Components: Weld Containers
    Affects Versions: 1.0.0.Alpha4
         Environment: Weld 1.1.0.Beta1
            Reporter: Lincoln Baxter III


ServiceLoader needs to be used to load the extensions and add then to the D=
eployment:
