using gij on Gnome:

huo@bisonws0135:~/temp$ java -version
java version "1.5.0"
gij (GNU libgcj) version 4.2.3 (Ubuntu 4.2.3-2ubuntu6)

Copyright (C) 2007 Free Software Foundation, Inc.

The installer switches to headless mode:

huo@bisonws0135:~/temp$ gij -jar jython_installer-2.5a3.jar

huo@bisonws0135:~/temp$ 

But then gij returns a non existing java.home:

huo@bisonws0135:~/bin/jython-2.2.1$ java -jar jython.jar
Jython 2.2.1 on java1.5.0
Type "copyright", "credits" or "license" for more information.
>>> from java.lang import System
>>> from java.io import File
>>> javahome = File(System.getProperty("java.home"))
>>> javahome
/usr/lib/jvm/java-1.5.0-gcj-4.2-1.5.0.0/jre
>>> javahome.exists()
0
>>> 

This could be related to:

I'll check if the installer could fallback to plain 'java' if the
java.home provided by gij does not exist.
