[jboss-jira] [JBoss JIRA] (WFLY-9081) Support ServletContainerInitializer placed on WARs

cnsgithub cnsgithub commented on WFLY-9081:
-------------------------------------------

I think something related to this, broke something with WF12 when using Spring. Currently i can't provide a *.war to test but a class residing in the *.war classes path is no longer recognized.

import org.springframework.web.WebApplicationInitializer;
public class MyWebApplicationInitializer implements WebApplicationInitializer  

09:52:16,244 INFO  [io.undertow.servlet] (ServerService Thread Pool -- 51) No Spring WebApplicationInitializer types detected on classpath

org.springframework.web.SpringServletContainerInitializer
@Override
	public void onStartup(@Nullable Set<Class<?>> webAppInitializerClasses, ServletContext servletContext)

->> WebAppInitializerClasses does not contain the MyWebApplicationInitializer anymore

Ultimately this call is coming from: WarMetaDataProcessor

I hope this is enough to find the cause of this. The same configuration worked fine with WF11 Final.

> The Servlet spec only talks about the presence of ServletContainerInitializer's within JAR files bundled on the WAR. It says nothing about what to do when found on the WAR and Undertow is ignored them right now, which is spec complaint.
> However, WildFly has the only Servlet container I'm aware of that ignores that classes, having tested Payara, WebLogic,WebSphere Liberty, Jetty, Tomcat and Resin.
> It would be good to support them on Undertow too. 
> I've also opened an issue on the Servlet spec repository, so this can be clarified for future versions of the document: https://github.com/javaee/servlet-spec/issues/179
