[jboss-jira] [JBoss JIRA] (WFLY-4200) WAR MDB cannot obtain superclass on module classpath

[Eduardo Silva (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-4200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13064795#comment-13064795 ] 

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

I believe that the problem is because AnnotatedEJBComponentDescriptionDeploymentUnitProcessor executes in the parse phase:

Phase.PARSE,Phase.PARSE_CREATE_COMPONENT_DESCRIPTIONS

Since the dependencies will be resolved at  Phase.DEPENDENCIES, your build will not work. 
Regarding WFLY, my suggestion is not throw the EjbLogger.ROOT_LOGGER.mdbDoesNotImplementNorSpecifyMessageListener(beanClass) only bring up some flag that the required interfaces were not yet resolved, some attachment could be useful, just to retain the super class name. When the dependencies were solved, the class will be present on the class index and the test against the annotation should be performed again. Since that work will be done twice, to verify the required interfaces, this requires some experts advice.

> 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.
