They are in test.classes (system property) I guess.

If you are willing to create MANIFEST.MF yourself (or suppose it's not necessary for you), it's also OK to open a ZipOutputStream, and (putNextEntry, write)*.

I should have clarified that of course one option is to simply run the jar tool programmatically :) But in that case I don't know how to tell it where to find the files that jtreg has compiled - are they simply in the current working directory? (Guess I can find out readily enough :) ).
