Under 2.2, a common use case for developers embedding jython was to wrap java objects in PyJavaInstance.

PyJavaInstance was deprecated in jython 2.5, so systems that embedded jython 2.2 and that want to upgrade to to jython 2.5 need an upgrade path.

Here are some examples

red5: http://code.google.com/p/red5/issues/detail?id=86
kepler: https://kepler-project.org/developers/reference/python-and-kepler
freemarker: http://sourceforge.net/tracker/index.php?func=detail&aid=3165425&group_id=794&atid=100794

Rather than let everyone trip over this one, let's document it. Ideally a document on the wiki describing the issue and illustrating a solution, with code that works under both 2.2 and 2.5.
