      Description

      My project has a JSF converter that is made injectable by Seam Faces. It extends the Seam Faces Converter abstract class:

      @FacesConverter("QueryField")
      @RequestScoped
      public class QueryFieldConverter extends Converter<QueryField<?>>
      

      In AS 7.1.1.Final, this is not a problem. In a recent AS 7.2.0.Alpha1 snapshot (which uses Weld 1.1.9.Final), I get the following exception:

      11:56:41,539 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-15) MSC00001: Failed to start service jboss.deployment.unit."Cerberus.ear".WeldService: org.jboss.msc.service.StartException in service jboss.deployment.unit."Cerberus.ear".WeldService: org.jboss.weld.exceptions.UnproxyableResolutionException: WELD-001435 Normal scoped bean class com.lapis.cerberus.status.query.QueryField is not proxyable because it has no no-args constructor - Managed Bean [class com.lapis.cerberus.portal.convert.QueryFieldConverter] with qualifiers [@Any @Default].

      If I'm not mistaken, Converter should be a bean type of QueryFieldConverter, but QueryField should not, given that QueryFieldConverter does not extend QueryField (which is an abstract class). Therefore, Weld should not be trying to proxy it.

      I attempted to work around this issue by using @Typed to specify which types should be considered bean types. The mere presence of that annotation results in this exception:

      11:50:54,213 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC00001: Failed to start service jboss.deployment.unit."Cerberus.ear".WeldService: org.jboss.msc.service.StartException in service jboss.deployment.unit."Cerberus.ear".WeldService: java.lang.NullPointerException
