Alas, I'm purely a user as far as jtreg goes. I've had odd looking errors myself and in those cases the eventual answer was often that I was running the wrong (too old) version of jtreg.
I hunt jtreg down from an internal build archive so I can't point you at what I use (nor provide it) but all the external contributors must have some favoured place to get their copy. I just don't know what it is. the code-tools list might be able to help.

But if you want to expedite this, just make the one change - I already tested it.
