Shutdown hook doesn't work in Eclipse [duplicate]

Answer 1

If you just want to test if the hook is working or not, throw new RuntimeException() from the trigger point. This should call the shutdown hook even from Eclipse.

Answer 2

Red stop button just terminates the application and according to eclipse devs they can't do anything about it see this issue in eclipse bug tracker.

Answer 3

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 4

I know I'm a bit late to the party, but I found this thread seeking for help and so will probably others.

We had the same issue and solved it with an Eclipse plugin (on Linux) which provides additional stop buttons now. I hope this serves all of you as well as it did help us :)

Answer 5

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.

@Pacerier - From the Javadoc: In rare circumstances the virtual machine may abort, that is, stop running without shutting down cleanly. This occurs when the virtual machine is terminated externally, for example with the SIGKILL signal on Unix or the TerminateProcess call on Microsoft Windows. The virtual machine may also abort if a native method goes awry by, for example, corrupting internal data structures or attempting to access nonexistent memory. If the virtual machine aborts then no guarantee can be made about whether or not any shutdown hooks will be run.
