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

[Emond Papegaaij (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-9488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13487367#comment-13487367 ] 

Emond Papegaaij commented on WFLY-9488:
---------------------------------------

[~mkouba] {{app-core.jar}} does contain a {{beans.xml}} with {{bean-discovery-mode="annotated"}}. However, the classes involved are not beans. They are Wicket components and do not conform to the requirements of a CDI bean. For example, many don't have a default constructor as Wicket requires an String id as a parameter to the super constructor. These are instantiated from user code and injected from inside the super constructor by Wicket. The reason they end up in 'additional' probably is because they are not CDI beans but are injected as non-contextual objects.

> 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.
