Hi Marc,

Good questions . . .

Yes, I'm fairly certain Java 1.6 can be used.
I'll update

Actually, not that stupid a question.

I'm fairly certain Kepler uses Jython 2.2. or Jython 2.2.1
Kepler-2.2 has
./Kepler.app/Contents/Resources/Java/core-2.2.0/lib/jar/jython.jar
that file is almost the same size as the jython.jar file used in the Kepler
development version at
./ptolemy/src/lib/jython.jar

I unjar'd and diffed the two and it seems like the have the same .class 
files.

The changelog for ./ptolemy/src/lib/jython.jar is below:

I have not tried to debug Jython code from within Kepler, but it should 
be doable.
You should be able to set breakpoints in the Jython code.  I suggest 
getting the Jython 2.2.1
source code as well.

Also, try searching the kepler-users group for Jython, you might find 
some interesting information.
