Ah, that's quite possible: if Jython's code path into JFFI causes mixing
between JFFI versions.

Hopefully an update to a newer Jython would fix it. Niko Ehrenfeuchter
tested this and uploaded it to the unibas update site; if you activate
that update site, maybe it will work for you even in the presence of
jruby-complete?

Ideally, of course, we would have only non-fat .jar files (i.e. .jar files
that do not bundle other dependencies within). It will be a major
undertaking, I fear, so I won't be able to tackle it at least until June.

Ciao,
