I can throw an exception instead, but it's odd since this is supposed to pass in this scenario. Still open to suggestions.

Well, the frames aren't being disposed, so the VM isn't going to exit() on its own.
You need to make sure that is done in both the parent and the exec'd chilld

I don't see an issue with calling System.exit(0) from the exec'ed child.
ie so long as it is ONLY from the child process, not the test launched by jtreg.
You'd need to do this if you wanted to signal any non-default condition.
