Почему не пропускает такой вариант?

public class Solution {

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

        try (BufferedReader reader = new BufferedReader(new FileReader(args[0]));
        BufferedWriter writer = new BufferedWriter(new FileWriter(args[1]))) {

            while (reader.ready()) {

                writer.write(new String(reader.readLine().getBytes("Windows-1251"), StandardCharsets.UTF_8));
            }
        }
    }
}
