Exception thrown with tutorial: CharToByteSingleByte

Bonjour

I am trying to use jsat on Sun Solaris:

java version: 1.3.1_01
jswat version: 20020426
classpath:
/usr/j2sdk1_3_1_01/lib/tools.jar:/local/jswat.jar:~/FTP
sourcepath: /usr/j2sdk1_3_1_01/src.jar:~/FTP

1)
With a very simple file: ~/FTP/HelloWorld.java
public class HelloWorld {
    public static void main (String[] args) {
                  System.out.println("Hello World");
                  }
}

cd ~/FTP
javac -g HelloWorld.java
java com.bluemarsh.jswat.Main works fine.

2)
With the file ~/FTP/tutorial.java provided with jswar

cd ~/FTP 
javac -g tutorial.java
java tutorial works *fine*: he application with the
button
press works

3)
But when I try to launch the same application tutorial
launched with java com.bluemarsh.jswat.Main.
The VM loading is OK, but VM running:

Exception thrown.
[main] CharToByteSingleByte.convert
(CharToByteSingleByte.java:154)
Could not find source file for class. Check classpath
and sourcepath.
(Method: sun.io.CharTobyteSingleByte.convert(char[],
...)

I have tried: jar -tf /usr/j2sdk1_3_1_01/src.jar |
grep -i CharTo
but this class is not found

Is someone get the same exception thrown ?

thank you for your help
F
