ой код:

try {
    String textLine;
    FileReader fr = new FileReader("ad.txt");
    BufferedReader reader = new BufferedReader(fr);
    while((textLine=reader.readLine()) != null) {
        textLine = reader.readLine();
        jTextArea1.read(reader, "jTextArea1");
    }
}
catch (IOException ioe) {
    System.err.println(ioe);
    System.exit(1);
}

И мой файл .txt содержит следующее:

Но показывает вывод, пропуская первые две строки.

Что является причиной этого?
