Unfortunately the actions need to happen after tomcat has shutdown, not
just my webapp.

I agree, but I don't have a choice, boss says it must kill itself if
some scenario happens.

When I call System.exit() tomcat doesn't actually shutdown, it looks
like it just is deadlocking or something as I am getting a timeout on
the call that runs it. On the bright side System.exit() does trigger the
shutdown hook to be called, even though the server doesn't shut down, it
just becomes unresponsive but the process remains and is still bound to
all of its ports.
If I call both,
org.apache.catalina.startup.Bootstrap.main(new String[] { "stop"});
System.exit(0);
Tomcat shuts down, and my hook gets called, but I don't know how
ridiculous I want to take this already hacky thing...
Probably stupid question, but is calling System.exit() from a webapp
supposed to be able to kill tomcat?
