Hi ,

I am getting below error in Test module when trying to create a new instance for jaxb context ,

Caused by: java.lang.ClassCastException: "PackageName.className"$JaxbAccessorF_FieldName cannot be cast to com.sun.xml.internal.bind.v2.runtime.reflect.Accessor

at com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl$JAXBContextBuilder.build(JAXBContextImpl.java:1127)

below is the code snippet on which it throws error

jaxbcontext = JAXBContext.newInstance(Classname.class);

Note :- The code works fine when deploying on a server and sending a request , but fails only in Test Module (We are using OpenEjb framework)

Can anyone help?

Thanks

Although I know nothing whatsoever about JAXB or OpenEjb, I know how
to do simple Web searches. Looking for "OptimizedAccessorFactory" led
me to

https://github.com/eclipse-ee4j/jaxb-ri/issues/1449

.... which you might find helpful.

Lots of detail there ...
