When Shutdown Hooks Break Bad

Question

If I add a shutdown hook to my Java program\'s runtime like so:

public class MyShutdownHook implements Runnable
{
    @Override
    public void run(         


        

Answer 1

If you pull the plug out the back of your computer then the shut-down hook won't run. Other situations include:

• The process being killed on a POSIX OS with SIGKILL (-9).
• Similarly if you elect to terminate an "unresponsive" process under Windows the shut-down hook may not complete.
