Thank you for such a quick answer - it wasn't what i did, but it helped me find the problem.
It seems an OS upgrade had upgraded the Java runtime, and that class is now neither provided nor called... but (and i should have mentioned this) my BaseX server was still running... i was worried about restarting the server in case it wouldn't work, until i resolved the problem, but in fact, restarting the server resolved it.
