Wildfly-14 : ClassCastException while marshalling/unmarshalling --------------------------------------------------------------- Key: WFLY-11549 URL: https://issues.jboss.org/browse/WFLY-11549 Project: WildFly Issue Type: Bug Affects Versions: 14.0.0.Final Reporter: Bhavesh Kharwa Assignee: Jason Greene Priority: Critical Attachments: hprofsnapshot.jpg I have configured wildfly-14 in domain mode and configured one profile "*full-ha-socket*" in domain.xml. Now I have deployed ear in wildfly.The application having functionality of marshalling/unmarshalling of content. Also I have provided jaxb dependency in maven as scope provided. So the issue is when I process the file the it throws classcastexception. Please refer below stackstrace. *Note: Sometimes it is working but sometimes giving exception* {code} Unhandled exception while procesing file 'testing.xml': java.lang.ClassCastException:

jboss-deployment-structure.xml - javax.mail.api - org.hibernate (slot=main) - javax.validation.api - com.sun.xml.bind (slot=main) - org.wildfly.clustering.singleton(slot=main) No duplicate classes/jars in application ear/lib... One thing I have noticed that if I undeploy & deploy the application then this issue start reproducing. One question: When I undeploy application, How can i verify application undeployed successfully (Removed all the application classes/lib from class loader while undeploy application)
