"""Run the built patch on the game's own Java 1.4.2, outside the game.

Uses the game's JVM, working directory and launch flags (including -Xfuture
strict class checks), so a class that loads here loads in the game. Runs the
harness twice: against the sidecar (start it first), then against a dead port to
prove the fallback to the original parser.
