In my opinion, the current directory is a good enough option. When run in jtreg, it is set to `scratch` which is empty when the test starts; when run manually as a standalone app, the chances you have other files named `000-0000000000` in the current directory are quite low. The test does not depend on the first file being displayed in the first row of the table, it looks for it; yet it depends on all the files being displayed in the sequence without alternating with other files.
