  platform.runlater(new runnable() {                   @override                     public void run() {                      wv = new webview();    final webengine engine = wv.getengine();              fxpanel.setscene(new scene(wv));      engine.setjavascriptenabled(true);    engine.load(url); } 

and when close frame when webview open can see them running in background , try close in 1 public void class not close how can it.

   public static void closeframe() {     platform.setimplicitexit(false);     if (classname != null) {         classname.frame.dispose();          platform.runlater(() -> {             wv = new webview();             classname.wv.getengine().reload();              classname.wv = null;             classname.frame = null;         }); 

exit platform in stop method this:

public class main extends application {      //entry point application     public static void main(string[] args) {         launch(args);     }      @override     public void start(stage primarystage) throws exception {         parent authscene = (parent) fxmlloader.load(getclass().getresource("/view/auth.fxml"));         scene scene = new scene(authscene);         primarystage.setscene(scene);         primarystage.setresizable(false);         primarystage.settitle("green project : login form");         primarystage.show();      }      @override     public void stop() {         platform.exit();     } }
