Fixed version (ground truth):
@Override public void actionPerformed(ActionEvent arg0){
  List<File> filesSelected=guiMain.getCurrentlySelectedMovieFileList();
  System.out.println("String_Node_Str" + filesSelected);
  try {
    WebReleaseRenamer webReleaseRenamer=new WebReleaseRenamer();
    for (    File currentFile : filesSelected) {
      System.out.println("String_Node_Str" + currentFile);
      System.out.println("String_Node_Str" + webReleaseRenamer.getCleanName(currentFile.getName()));
      System.out.println("String_Node_Str" + webReleaseRenamer.newFileName(currentFile));
      File newFileName=webReleaseRenamer.newFileName(currentFile);
      if (currentFile.getName().equals(newFileName.getName())) {
        System.out.println("String_Node_Str");
      }
 else       if (guiMain != null && MoviescraperPreferences.getInstance().getConfirmCleanUpFileNameNameBeforeRenaming()) {
        int optionPicked=JOptionPane.showConfirmDialog(guiMain.getFrmMoviescraper(),"String_Node_Str" + currentFile + "String_Node_Str"+ newFileName+ "String_Node_Str","String_Node_Str",JOptionPane.YES_NO_OPTION);
        if (optionPicked == JOptionPane.YES_OPTION) {
          boolean renameStatus=currentFile.renameTo(newFileName);
          if (renameStatus != true)           System.err.println("String_Node_Str");
        }
      }
 else {
        boolean renameStatus=currentFile.renameTo(newFileName);
        if (!renameStatus)         System.err.println("String_Node_Str");
