[jboss-jira] [JBoss JIRA] (WFLY-8815) WeldApplication should extend ApplicationWrapper

WeldApplication should extend ApplicationWrapper ------------------------------------------------ Key: WFLY-8815 URL: https://issues.jboss.org/browse/WFLY-8815 Project: WildFly Issue Type: Bug 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. {code} Caused by: java.lang.UnsupportedOperationException at javax.faces.application.Application.getSearchExpressionHandler(Application.java:2001) at javax.faces.application.ApplicationWrapper.getSearchExpressionHandler(ApplicationWrapper.java:815) at com.sun.faces.config.processor.ApplicationConfigProcessor.setSearchExpressionHandler(ApplicationConfigProcessor.java:738) at com.sun.faces.config.processor.ApplicationConfigProcessor.process(ApplicationConfigProcessor.java:382) at com.sun.faces.config.processor.AbstractConfigProcessor.invokeNext(AbstractConfigProcessor.java:155) at com.sun.faces.config.processor.LifecycleConfigProcessor.process(LifecycleConfigProcessor.java:138) at com.sun.faces.config.processor.AbstractConfigProcessor.invokeNext(AbstractConfigProcessor.java:155) at com.sun.faces.config.processor.FactoryConfigProcessor.process(FactoryConfigProcessor.java:246) at com.sun.faces.config.ConfigManager.initialize(ConfigManager.java:443) ... 20 more {code} This is reported a.o. here http://stackoverflow.com/questions/44076148/why-is-jsf-2-3-not-working-wi... 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.
