  • java.lang.ClassCastException: packageName$JaxbAccessorF_ cannot be cast

    From Abhishek jain@21:1/5 to All on Wed Aug 4 23:53:01 2021
    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.


    below is the code snippet on which it throws error

    jaxbcontext = JAXBContext.newInstance(Classname.class);

    Lots of detail there ...

    Look on my code, ye Hackers, and guffaw!
