Problem conclusion

  • For efficiency, the JAXB Marshaller generates new classes at
    runtime to assist in the marshalling of JAXB objects. The
    generated classes were occasionally being loaded into the wrong
    ClassLoader and that could result in a NoClassDefFoundError
    when one of the application's classes is accessed from the
    generated code.
    
    The issue was fixed by ensuring that the IBM JAXB Marshaller
    loads classes that it generates into the correct ClassLoader.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.23 and 8.0.0.1.  Please refer to the
