Looks good.
I would probably have had the hook interrupt the main thread while it
was running ie sleep(5000); main.interrupt(); sleep(5000); but
pre-interrupting itself before calling exit is probably functionally
equivalent.

The shutdown hooks race against the shutdown sequence if the thread
invoking System.exit() is interrupted. This happens because
ApplicationShutdownHooks::runHooks joins the shutdown hooks. This

executed.
