Are you seeking legal advice from the internet :-) ?

In a attempt to answer your question, you must comply with the license 
terms listed in all of the license files found in the installed jython 
directory:

   ./Lib/LICENSE
   ./LICENSE.txt
   ./org/apache/LICENSE

When embedding jython in an application or using jythonc to compile a 
python application, you will need to comply with the text in all three 
license files. It is not impossible to remove the apache component, but 
the jython license and the PSF license can't be avoided.

 From a legal POV I guess it is a nigthmare, but in reallity it isn't 
that hard to comply. Common sense and normal good open source behaviour 
is mostly enough.

- Don't sue anyone involved in any of the projects.
- Don't claim that you wrote stuff you didn't write.
- Include the licenses or license files from jython in your product.
- Don't use any of our names as endorsment of your stuff.

In addition, CNRI added som other demands:

- If you make changes to CNRI code and distribute the result, you must
   describe the changes.

But take the time to read the licenses yourself.

The good part is that you already have all the licenses you need, as 
long as you comply with the demands in the licenses. If you need some 
legal entity (like me) to permit you to use the jython libraries, that 
ain't going to happen.
