I tested your example problem and saw the same thing under linux.
However, I then read Conor's report

"Note that the use of output or error streams to determine if the shutdown hook
has fired or not is suspect. The above file based approach is more conclusive."

So, I changed the code to do:
	public class Shutter extends Thread {
		public void run() {
//			log.debug("clean shutdown");
                    System.err.println("DEMO shutdown hook fired");
                    try {
                        java.io.PrintWriter pw
                            = new java.io.PrintWriter(
                      new java.io.FileOutputStream("test.txt"));
                        Thread.currentThread().sleep(3000);
                        pw.println("Test");
                        pw.close();
                    } catch (Exception e) {
                    }
                    System.err.flush();
                    System.out.println("clean shutdown...");
		}
	}

And noted that clean shutdown... was not seen, but the file was created
and written to, and the DEMO shutdown hook fired message was seen.
Can you make the above changes and see if they fix the problem?
