[jboss-jira] [JBoss JIRA] (WFLY-9488) WeldDeployment initialisation error causes session fail-over to fail.

    [ https://issues.jboss.org/browse/WFLY-9488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13487264#comment-13487264 ] 

Martin Kouba commented on WFLY-9488:
------------------------------------

[~klaasjanb] Hm, it seems only _additional_ bean deployment archives are affected, i.e. the bean class does not come from any bean archive and was probably added by an extension. It would be great if you could provide some more info about the packaging and deployment structure, e.g. where does the problematic {{AnnotatedType}} come from?

> At Topicus we've tested one of our Java EE applications to check compatibility with Wildfly session replication. This resulted in deserialization errors when performing a failover test.
> (WELD-001122: Failed to deserialize annotated type identified with AnnotatedTypeIdentifier)
> The application is deployed as an EAR archive containing several modules, one of them a WAR which hosts the main web frontend.
> Point of interest is our application uses Wicket (with Wicket-CDI) to inject CDI resources in Wicket pages.
> After a debugging session we concluded the "tryToLoadUnknownBackedAnnotatedType" method in the Weld class "SlimAnnotatedType" uses the wrong ResourceLoader when trying to load the class containing an injected object.
> Further debugging proved the initialisation in the WeldDeployment method "createAndRegisterAdditionalBeanDeploymentArchive" copies all of the ServiceRegistry entries of the parent BeanDeployment to the child, overwriting the already set ResourceLoader.
> I've attached a patch which prevents the overwriting of the deployment's already set entries. This fixed the replication problems with our application.
