Further research. Support in Jython first appears here:
https://hg.python.org/jython/rev/f6b3ddbc1df8
on the eve of the release of 2.7.1, so if you're using 2.7.1 it ought to work but with 2.7.0 it won't.

The 2.7.1 JAR is hard to find (never understood why) and I'm also conscious of a bug that may discourage use in high-performance multiprocessor applications.

In relation to this being a jnr/jffi problem, this is relevant: https://github.com/jnr/jffi/pull/11, and the tangle of PRs and issues you can reach from it. Collectively, it looks like jnr/jffi support works.

If we assume jnr/jffi actually works, it may simply be that clients are using the 2.7.0 JAR.
