This is a similar results to my efforts.  Interestingly, the permission
errors seemed to disappear upon reordering the classpath - no idea why.  But
then, my robot failed as my (your) pyrobot classs wasn't a subclass of
Robot.  Ooops, I wasn't linking in the robocode.jar.  When I changed that
back, I could no longer 'jythonc' my code.  Frustrating.  I'll try again
with a more controlled approach.  Good luck to you.
