Again, that seems weird. Do you have some kind of deadlock occurring
in your shutdown code? It sounds like:
System.exit: calls your shutdown hook, JVM does not stop
Bootstrap.main({"stop"}): avoids your shutdown hook, JVM stops
Maybe you should check your shutdown hook. :)

It's a pretty ridiculous hack in any case, right?

Yes. It should kill the JVM, which should shut down everything. If you
want to protect your JVM from webapps that might call System.exit(),
then you need to run under a SecurityManager.
