There is a hook in the runtime to enable this if you want.

BUT, null pointer exception or not, Adam is right. Have your 
stuff run in multiple process that you can restart. This is more 
reliable, this is more secure, this is easier to update without 
downtime, and so on... This is far superior solution for server 
stuff.
