Wildfly-14 : ClassCastException while marshalling/unmarshalling

[bhavesh.rkharwa]

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

Unhandled exception while procesing file 'testing.xml': java.lang.ClassCastException: com.commons.impl.NewsMessageImpl cannot be cast to com.commons.NewsMessage

Also i have added following dependencies in 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)

Can you please suggest what is wrong in this.

[ctomc]

do you maybe have some duplicate classes / jars in your ear/lib and war/WEB-INF/lib

that could explain this error.

[bhavesh.rkharwa]

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)
