      As I was trying to use a file contained in the JAR of my addon, I used this (intuitive) code

      URL voilaURL = getClass().getClassLoader().getResource("voila.txt");
      File f = new File(voilaURL.toExternalForm());

      Resource<?> resource = rfactory.create(f); // KO
      FileResource fresource = rfactory.create(FileResource.class, f); // KO

      both last two line lead to a FileResource which, in debug is displayed as this form
      [PROJECT_ROOT][Correct full path of file in jar]

      D:\workspace_addons\ADDONS\jar:file:\C:\Users\me\.forge\addons\fr-company-addons-ADDONS213b-1-0-1-SNAPSHOT\ADDONS213b-1.0.1-SNAPSHOT-forge-addon.jar!\voila.txt

      Then, those FileResources when used with the templateFactory
      Template template = tfactory.create(resource,FreemarkerTemplate.class);

      lead to an error like "template does not exist"

      Hint?: The toString value is wrong but the path of the file within FileResource is ok

      See https://developer.jboss.org/thread/252367 for more data
