jython license review

[stack]

Over in hbase-land we're evaluating replacements for our SQL-like shell 
(HBASE-487).   An amended jython is a possibility but  I was wondering 
if the license was Apache-amenable?  It looks OK to me -- 
http://www.jython.org/Project/license.html -- but I'm not an expert.

JRuby and beanshell for sure won't work because of license.
Groovy is a possibility; its Apache licensed and integration was 
straight-forward.

Anything else folks thing we should be looking at?

Thanks,
