Buggy source:

Fixed version (ground truth):

        throw new AndrolibException("String_Node_Str" + fileName);
      }
    }
 catch (    IOException|RecognitionException ex) {
      throw new AndrolibException(ex);
    }
    return;
  }
  if (!fileName.endsWith("String_Node_Str")) {
    LOGGER.warning("String_Node_Str" + inFile);
    return;
  }
