Use a shutdown hook:

Runtime.getRuntime().addShutdownHook(new Thread() {
    public void run() {
        // log here
    });

You'll have to register a shutdown hook

Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {            
    @Override
    public void run() {
        // do your thing
    }
}));

Note that this will only get executed if the program ends naturally.
