No me funciona System.in

El archivo 'texto-copia.txt' no se me actualiza con el contenido ingresado por consola, queda vacío. No sé que estoy haciendo mal

public class TestCopiarPegar {

    public static void main(String[] args) throws IOException {

        InputStream fileInputStream = System.in;
        Reader inputStreamReader = new InputStreamReader(fileInputStream);
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

        OutputStream fileOutputStream = new FileOutputStream("texto-copia.txt");
        Writer outputStreamWriter = new OutputStreamWriter(fileOutputStream);
        BufferedWriter bufferedWriter = new BufferedWriter(outputStreamWriter);


        String linea;
        while ((linea = bufferedReader.readLine()) != null) {
            bufferedWriter.write(linea);
            bufferedWriter.newLine();
        }

        bufferedWriter.close();

    }

}
