Klaasjan Brand created WFLY-9488: ------------------------------------ Summary: WeldDeployment initialisation error causes session fail-over to fail. Key: WFLY-9488 URL: https://issues.jboss.org/browse/WFLY-9488 Project: WildFly Issue Type: Bug Components: CDI / Weld Affects Versions: 11.0.0.Final Environment: Testen on OS X Sierra with Oracle JDK 1.8.0_152 Reporter: Klaasjan Brand Assignee: Martin Kouba Attachments: serviceregistry.patch 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. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
