I don't see anything obvious, the seed doesn't reproduce for me either.

The crux is that in the ZkMaintenanceUtils I have the line:

Files.createFile(file);

then in the test this fails:

assertTrue("Empty files should NOT be copied down as directories",
locEmpty.toFile().isFile());

where it should point to the same file (created in a temporary
directory) that the Files.create created. Beasting now since it works
every time I've run it so far on my mac. Maybe getting defeated by
some randomization trickery.

I may have to put in some debugging info if I can't get a beast failure.
