Load external images in JavaFX - image

Question

I am trying to load external images using JavaFX, but since using the new raspberry 4, I am unable to load external images, I can however load images internal to the Jar file.
as an example I have attached the code below. this works on my mac and raspberry pi3 but does not work for the raspberry pi 4 running Debian Buster, the only difference between the raspberry pi 4 and the there computers is that the RPI4 is running the latest JavaFX openjdk 14.0.1 and the other computers are running version 1.8.0_20.
on all instances i get a print of true for System.out.println(file.exists());
the RPI4 can load images inside the Jar, any help please
Code:
package application;
import java.io.File;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
Scene scene = new Scene(setupScene(), 300, 300);
primaryStage.setScene(scene);
primaryStage.setTitle("Image Screen");
primaryStage.show();
}
StackPane setupScene() {
StackPane root = new StackPane();
ImageView imageView = new ImageView();
imageView.setPreserveRatio(true);
imageView.setSmooth(true);
File file = new File("/home/pi/dscf4452.jpg");
System.out.println(file.exists());
System.out.println(file);
Image image = new Image(file.toURI().toString());
// Image image = new Image(getClass().getClassLoader().getResource("test.jpg").toString());
imageView.setImage(image);
root.setPrefSize(250, 250);
imageView.setFitHeight(root.getPrefHeight());
imageView.setFitWidth(root.getPrefWidth());
root.getChildren().add(imageView);
return root;
}
}
