I don’t know if this helps. It could be because of openjdk vs oracle. In FileSystems.java in the oracle JDK getDefault loads: sun.nio.fs.DefaultFileSystemProvider.create() I imagine that openjdk wouldn’t use that, perhaps. So, maybe using the oracle JDK would work. Kendall

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.
