Shutdown hook doesn't work in Eclipse [duplicate]

Question

I have added a shutdown hook via:

Runtime.getRuntime().addShutdownHook(myShutdownHook); 

It works fine normally, but not when I click the red stop button in Eclipse. Is there a way to make the shutdown hook be called in Eclipse?

Answer 1

The red stop button forcibly kills the application, i.e. not gracefully, so the JVM doesn't know that the application is exiting, therefore the shutdown hooks are not invoked.

Unfortunately, there is no way (in Windows, at least) to provide a mechanism that ensures that the hook is always invoked. It's just something that may be invoked, but there is no guarantee.

Answer 2

I made a hack by replacing JavaProcess with decorated one:

    IProcess p = launch.getProcesses()[0];     launch.addProcess(new JavaProcessDecorator(p));     launch.removeProcess(p); 

And decorator is overriding terminate function.

public class JavaProcessDecorator implements IProcess {  private IProcess p;  public JavaProcessDecorator(IProcess p) {     this.p = p; }  private boolean sigkill = false;  @SuppressWarnings("rawtypes") @Override public Object        getAdapter(Class arg)                { return p.getAdapter(arg); } ... @Override public ILaunch       getLaunch()                          { return p.getLaunch(); } @Override public IStreamsProxy getStreamsProxy()                    { return p.getStreamsProxy(); } @Override public void          setAttribute(String s1, String s2)   {        p.setAttribute(s1, s2); } @Override public void          terminate() throws DebugException    {     if(!sigkill) {         try {             IDebugIService cs = DirmiServer.INSTANCE.getRemote("main", IDebugIService.class);             if(cs != null) cs.modelEvent(new TerminateRequest());         } catch (RemoteException e) { }         this.sigkill = true;     } else p.terminate(); }} 

At first click on red button, I send a message to application asking for gently termination. If it is not working, second click on red button will kill it.
