File Reader error in J-Link

Hi, I have problem with FileReader function. I can read info of file, but I cant read content.

    String fileName = "d:\\ProUser\\text.txt";

    File file = new File(fileName); //works good

    if(file.canRead()== true){

      DisplayMessage.infoMessage ( "Nacten cfg soubor: "+file.getParentFile()+"\\"+file.getName()+", absolutni cesta: "+file.getAbsolutePath()); //works good

     FileReader fr = new FileReader(file); //error

      fr.close();      //error

    }else{

            DisplayMessage.errorMessage ( "Nelze nacist soubor: "+fileName);

    }

Any idea?

Thanks
