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

             Summary: Deployments fails if AsyncListener in WEB-INF/classes or in a jar in WEB-INF/lib implements a class that isn't on the classpath
                 Key: WFLY-8518
                 URL: https://issues.jboss.org/browse/WFLY-8518
             Project: WildFly
          Issue Type: Bug
          Components: EE
    Affects Versions: 9.0.2.Final, 10.1.0.Final
            Reporter: Andy Wilkinson
            Assignee: Stuart Douglas


If a web application contains, anywhere in {{WEB-INF/classes}} or a jar in {{WEB-INF/lib}}, an {{AsyncListener}} that implements an interface that isn't on the classpath, deployment of the web application will fail. A concrete example is Spring Framework's {{spring-web}} module which contains [such a listener|https://github.com/spring-projects/spring-framework/blob/f716c8e9bc8ada04b4060e21680aca793e315cd0/spring-web/src/main/java/org/springframework/http/server/reactive/ServletHttpHandlerAdapter.java#L152].

When a war file is deployed to Wildfly 9.0.2.Final with {{spring-web}} in {{WEB-INF/lib}} deployment fails:

This listener is only ever actually registered when the {{Subscriber}} class is on the classpath so it seems unreasonable for it to cause a failure at deployment time.

I'll attach a very basic example that triggers a similar problem. In the case of the example it fails with the following upon deployment to Wildfly 10.1.0.Final:
