I have added a bugreport about it, but I doubt I'll bother to fix it.
Jythonc does a static analysis of all the assignments going on in the
python script and this analysis does not handle re-assignments to the
same name. I agree that jythonc can be improved so it recognizes that
Panel is obviously bound to the same value.
