Fixed version (ground truth):

    }
    return decorateText;
  }
 else   if (input.endsWith(PluginConstant.ANA_SUFFIX)) {
    IFile fileElement=(IFile)element;
    if (log.isDebugEnabled()) {
      log.debug("String_Node_Str" + (fileElement).getLocation());
    }

    if (analysis != null) {
      Date executionDate=analysis.getResults().getResultMetadata().getExecutionDate();
