someone who said :

Are you sure you really do System.exit()

I do a real system exit.

SSCCE?

pittsdosx:noisebridge pittsd$ cat ExitTest.java
public class ExitTest {
    public static void main(String...args) throws Exception {
      new Thread(new Runnable() {
         public void run() {
            while(true) {
              System.out.println("In thread!");
              try {
               Thread.sleep(250);
              } catch (Exception e) {
                e.printStackTrace();
              }
           }
        }}).start();

      Thread.sleep(2000);
      System.out.println("Before exit!");
      try {
        System.exit(-1);
      } finally { System.out.println("Finally!"); }
    }

I see no evidence that the thread continues after System.exit() is
finished executing.

Granted, I do see a slight delay, probably due to thread scheduling,
that my log message for the "before exit" isn't the last thing output.
