在Java中将元素转换为对象不起作用

Question

我使用以下代码将元素xml转换为对象：

    public static Object xmlToObject(Element element, Class c, org.apache.logging.log4j.Logger log) {
    try {
        if (log != null) {
            log.debug(element);
            log.debug("este es el resultado ");
        }
        JDOMSource source = new JDOMSource(element);
        JAXBContext context = JAXBContext.newInstance(c);
        Unmarshaller un = context.createUnmarshaller();
        return un.unmarshal(source);
    } catch (JAXBException ex) {
        java.util.logging.Logger.getLogger(SiodexClient.class.getName()).log(Level.SEVERE, null, ex);
    }
    return null;
}

在weblogic 10中也可以正常运行并且可以控制台Java正常执行，但是在weblogic 12中为什么不起作用？

这是错误：

   [Exception [EclipseLink-25008] (Eclipse Persistence Services - 2.6.5.v20170607-b3d05bd): org.eclipse.persistence.exceptions.XMLMarshalException
