-----------------------------------

             Summary: WeldApplication should extend ApplicationWrapper
                 Key: WFLY-8815
                 URL: https://issues.jboss.org/browse/WFLY-8815
             Project: WildFly
          Issue Type: Feature Request
          Components: CDI / Weld
    Affects Versions: 10.1.0.Final
         Environment: WildFly 10.1.0.Final with JSF 2.3
            Reporter: Bauke Scholtz
            Assignee: Stuart Douglas


When upgrading WildFly 10.x to JSF 2.3, then running a web application using any JSF library having a custom javax.faces.application.Application will result in an UnsupportedOperationException during startup.

This is reported a.o. here http://stackoverflow.com/questions/44076148/why-is-jsf-2-3-not-working-with-omnifaces-2-6-1

This problem has the same grounds as reported in a.o. https://github.com/omnifaces/omnifaces/issues/75 and https://issues.jboss.org/browse/WELD-1805

Root problem is: {{org.jboss.as.jsf.injection.weld.WeldApplication}} does not extend from JSF's own `javax.faces.application.ApplicationWrapper` having all necessary default methods implemented. Instead, it extends from a custom {{org.jboss.as.jsf.injection.weld.ForwardingApplication}} with only JSF 2.2 specific default methods hardcoded instead of relying on API-provided ones.

Solution: let {{WeldApplication}} extend from {{ApplicationWrapper}} instead.
