JavaFX could not create platform window

User_HLZR7 · Sep 9, 2020 5:19AM

Hi,

we have a JAvaFX application running. Sometimes the application crashes with the following exception.

It's OpenJDK 11 with OpenFX14 running on Windows 10 machines.
Any idea what can cause this problem

java.lang.RuntimeException: could not create platform window

Yes.

I have discovered the same problem in java 16 and all the way back to java 11.

If I run the following code:

package test;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.layout.StackPane;

import javafx.stage.Popup;

import javafx.stage.Stage;

public class TestFX extends Application {

@Override

public void start(Stage primaryStage) {

System.out.println("javafx.runtime.version: " + System.getProperties().get("javafx.runtime.version"));

Stage stage = new Stage();

Scene scene = new Scene(new StackPane());

stage.setScene(scene);

stage.show();

Popup popOver = new Popup();

for (int i = 0; i < 99999; i++) {

popOver.show(scene.getRoot(), 1, 1);

popOver.hide();

System.out.println(i);

}

public static void main(String[] args) {

launch(args);

}

It will crash with after some iterations, it can vary.

the error stacktrace:
