Eduardo Silva commented on WFLY-4200:
-------------------------------------

The error is getMessageListenerInterface of MessageDrivenComponentDescriptionFactory:

private String getMessageListenerInterface(final CompositeIndex compositeIndex, final AnnotationInstance messageBeanAnnotation) throws DeploymentUnitProcessingException {
        final AnnotationValue value = messageBeanAnnotation.value("messageListenerInterface");
        if (value != null)
            return value.asClass().name().toString();
        final ClassInfo beanClass = (ClassInfo) messageBeanAnnotation.target();
        final Set<DotName> interfaces = new HashSet<DotName>(getPotentialViewInterfaces(beanClass));
        // check super class(es) of the bean
        DotName superClassDotName = beanClass.superName();
        while (interfaces.isEmpty() && superClassDotName != null && !superClassDotName.toString().equals(Object.class.getName())) {
            final ClassInfo superClass = compositeIndex.getClassByName(superClassDotName);
            if (superClass == null) {
                break;
            }
            interfaces.addAll(getPotentialViewInterfaces(superClass));
            // move to next super class
            superClassDotName = superClass.superName();
        }

        if (interfaces.size() != 1)
            throw EjbLogger.ROOT_LOGGER.mdbDoesNotImplementNorSpecifyMessageListener(beanClass);
        return interfaces.iterator().next().toString();
    }


beanClass = org.warmdbtest.MyWarMDB
superClassDotName = org.mdbtest.MySuperListener
compositeIndexValues =>   {org.warmdbtest.MyWarMDB=org.warmdbtest.MyWarMDB}
So superClassDotName org.mdbtest.MySuperListener is not indexed, 
This breaks anc the DeploymentUnitProcessingException is called
 if (interfaces.size() != 1)
            throw EjbLogger.ROOT_LOGGER.mdbDoesNotImplementNorSpecifyMessageListener(beanClass);

>    Affects Versions: 8.2.0.Final

> see the forum post for details:
> https://developer.jboss.org/message/914355
> but suffice it to say this is similar to https://issues.jboss.org/browse/AS7-2638 which appears to have come back again.
> In my WAR, I have an MDB which extends a class (in which that superclass implements MessageListener) and that superclass is in a module that my WAR depends on; the MDB fails to deploy. I have to explicitly add an annotation attribute to workaround the problem.
> Again, see the forum for the very easy steps to replicate with a small zip file that contains the replication code.
