Jython & Free-Java-SDK

[Andrew Malcolmson <andzy@imap-mail.com>]

Although SableVM (as part of the free-java-sdk package) is not listed by the
Jython project as a supported Java VM, I thought I'd try it anyway, and sure
enough running the Jython interpreter exits with 

java.lang.NullPointerException
   at gnu.java.lang.SystemClassLoader.systemFindResource (SystemClassLoader.java :294)
   at gnu.java.lang.SystemClassLoader.getResource (SystemClassLoader.java:175)
   at gnu.java.lang.SystemClassLoader.findClass (SystemClassLoader.java:79)
   at java.lang.ClassLoader.loadClass (ClassLoader.java:332)
etc.

Anyone had better luck with this?
