Kaffe's native2ascii tries to execute sun.tools.native2ascii.Main,
which cannot be found.

Here is my native2ascii which can be used with kaffe.

$ cat kaffe/tools/native2ascii/Main.java
package kaffe.tools.native2ascii;
import java.io.*;

public class Main {

    public static void main(String[] args) {

        String encoding = System.getProperty("file.encoding");
        String input = null;
        String output = null;

        for (int i=0; i<args.length; i++) {
            if(args[i].equals("-encoding")) {
                i++;
                if (i >= args.length) {
                    System.err.println("encoding is missing");
                }
                else {
                    encoding = args[i];
                }
            }
            else if (args[i].equals("-reverse") || args[i].startsWith("-J")) {
                System.err.println(args[i] + ": not supported");
            }
            else {
                if (input == null) {
                    input = args[i];
                }
                else if (output == null) {
                    output = args[i];
                }
                else {
                    System.err.println(args[i] + ": ignored");
                }
            }
        }

        try {
            InputStream is = (input == null ?
                System.in :
                new FileInputStream(input));
            OutputStream os = (output == null ?
                (OutputStream)System.out :
                new FileOutputStream(output));
            BufferedReader rdr =
                new BufferedReader(
                    new InputStreamReader(is, encoding));
            PrintWriter wtr =
                new PrintWriter(
                    new BufferedWriter(
                        new OutputStreamWriter(os, encoding)));
            while (true) {
                String s = rdr.readLine();
                if (s == null) break;
                StringBuffer sb = new StringBuffer(s.length() + 80);
                for (int i = 0; i < s.length(); i++) {
                    char c = s.charAt(i);
                    if (c <= 0xff) {
                        sb.append(c);
                    }
                    else {
                        sb.append("\\u" + Integer.toHexString((int)c));
                    }
                }
                wtr.println(sb.toString());
            }
            rdr.close();
            wtr.flush();
            wtr.close();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}
