code: @Override
    public void onFileDelete(Path rawPath) {
      URI jobSpecUri = this.converter.computeURI(rawPath);
      // TODO: fix version
      listeners.onDeleteJob(jobSpecUri, null);
    }
docs: For already deleted job configuration file, the only identifier is path

  @param rawPath This could be the complete path to the newly-deleted configuration file.
