Problem start JSWAT

Hi,

I downloaded JSwat and tried starting it, but it does not come up - it gets stuck right away withouyt opening a second window or
printing any output.
I tried running it under JDK 1.3.1 but it didnt have the logging classes available (part of JDK 1.4 I guess...)
So I downloaded and installed JDK 1.4.2 and now it does not start up, but I dont get any errors either.

Since I need JDK 1.3.1 for my IDEs etc, overwrote java.exe and javaw.exe in the system32 directory with the old 1.3.1 versions and
also changed the CurrentVersion pointers in the registry back to 1.3
I then run the 1.4.2 java.exe directly by calling
"C:\progra~1\Development\jdk1.4.2\bin\java" -Djava.ext.dirs="C:\progra~1\Development\jdk1.4.2\lib" -jar
"c:\progra~1\Development\jswat-2.17\jswat.jar"

This should work, I can call "C:\progra~1\Development\jdk1.4.2\bin\java -version" and java runs and prints the version info for
1.4.2...
It's just JSwat that doesnt start up. using javaw.exe instead of java.exe just exits right away without errors

Does anybody have any ideas?

In case this is related to my modifications of the JDK installation, what other way is there to run JSwat under JDK 1.4 while
running all the programs I want to debug under JDK 1.3? Or can I download an older version of JSwat that runs under 1.3.1?


Thanks,
