      Expected behavior

      Though there is ongoing work to see how/if to keep making JAXB usages in Jenkins on Java 11+, it would be nice if the plugin code could be analyzed to see if it could work without depending on JAXB API (which has been removed from the JDK starting from Java 9+).

      Technical consideration

      Looking at the code quickly, I think the main (only?) reason JAXB usage is to marshall/unmarshall the ClocReport.

      I think replacing the serialization with an XStream marshalling would probably achieve the same thing, while removing the JAXB dependency.
