In fact for proper SA test coverage, it is more important for the test args to be passed to the debuggee than to be passed to the test or the the SA tool that the test launches. For a couple of jhsdb tests that launch jshell as the debuggee, this wasn't happening, and jshell was always launched with no extra args.
