SecurityManager exception

Code Java:

---

import java.lang.*;
public class java17_test extends SecurityManager{
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
 
 
		System.setSecurityManager(new securityHouse());
		System.exit(1);
 
	}
 
}
 
 
class securityHouse extends SecurityManager{
	public void house(){
		 checkExit(1);
 
		}
	}

---

I expected to get a SecurityException as soona as I invoked the System.exit(1) method but I failed to get one..
Is my logic right?

What does the house() method do? Who calls it?

You need to have a security configuration file with this as well or override some methods on the SecurityManager that check to see if you're allowed to call System.exit(int);
