Jython inherit from Java class

[Mark Fink]

I observed something strange when I tried to compile the jython class:
D:\AUT_TEST\workspace\JyFIT\fit>jythonc JyFitServer.py
processing JyFitServer

Required packages:
  fitnesse.util
  java.io
  java.net
  fitnesse.components*

Creating adapters:

Creating .java files:
  JyFitServer module
    JyFitServer extends fit.FitServer

ERROR DURING JAVA COMPILATION... EXITING

D:\AUT_TEST\workspace\JyFIT\fit>
Looks like something in the Jython core causes the problem
(org\python\core\Py.java) any Ideas what I can do?
