JavaFX on Ubuntu 22.04 won't work like on Windows 10

I have ported some JAVA Apps from Windows 10 onto Ubuntu 22.04 (it runs alongside with Windows). Some data:

• Acer e15. 360 GB Ubuntu-partition
• Java JDK-9.0.4 (I won't move up due to one fact that JavaFX is a part of JDK and it saves me to deal with Open JavaFX) for both Windows and Ubuntu.

Most of the apps work fine. However I have noticed that JavaFX GraphicsContext won't work with Image on Ubuntu. On Windows 10 it works fine. The codes are

  scopter = new Image(getClass().getResourceAsStream("scopter.jpg"));
  Canvas screen = new Canvas(580, 500);
  gc = screen.getGraphicsContext2D();
  ...
  private void draw( ) {
    gc.setFill(Color.BLACK);
    gc.fillRect(0,0,580,580);
    gc.setFill(Color.RED);
    gc.drawImage(scopter, sX, sY); // <---Trouble is HERE
    if (mode) { // pick-up mode
      if (home > 1) { // chopper home
        gc.fillOval(cX, cY, 15, 15);
      } else if (home > 0) { // cargo home
        gc.fillOval(sX+DX, sY+DY, 15, 15);
      } else { // on fetching cargo
        if (home < 0) { // outbound
          gc.setStroke(Color.RED);
          gc.fillOval(cargoX, cargoY, 15, 15);
          gc.strokeText("Invalid Cargo Location.", 200, 250);
        } else gc.fillOval(cX, cY, 15, 15);
      }
    } else { // delivery mode
      if (home > 0) { // chopper home
        gc.fillOval(dX, dY, 15, 15);
      } else { // on fetching cargo
        if (home < 0) { // outbound
          gc.setStroke(Color.RED);
          gc.fillOval(cargoX, cargoY, 15, 15);
          gc.strokeText("Invalid Cargo Location.", 200, 250);
        } else {
          if (delivery > 0) {
            gc.fillOval(sX+DX, sY+DY, 15, 15);
          } else gc.fillOval(cargoX, cargoY, 15, 15);
        }
      }
      if (dX > 0) {
        gc.setFill(Color.WHITE);
        gc.fillOval(dX+5, dY+5, 5, 5);
      }
    }
    gc.setLineWidth(1);
    gc.setStroke(Color.YELLOW);
    gc.strokeText("FuzzyLogic Controlled Aerial Chopper - Joe Nartca (C) -", 124, 15);
    gc.strokeText(String.format("Speed %3.2f, Chopper %3.2f / %3.2f (cargo %3.2f / %3.2f)",
                                speed, sX, sY, cX, cY), 108, 30);
    gc.setStroke(Color.CYAN);
    gc.strokeText(String.format("Distance to TARGET and GOAL  %3.2f / %3.2f",
                                deltaX, deltaY),5, 495);
    if (oX != 0) {
      gc.setFill(Color.web("#a9ff00"));
      gc.fillOval(oX, oY, 20, 20);
    }
  }

The Screen layout And as one can see that the scopter image aside the red ball won't show up. The question is: is it a glitch of Ubuntu 22.04 or of JavaFX-linux?

PS: And here is the Image on Windows

...I found the problem that makes me thinking about the bug whether it is JFX bug (JDK 9.04) or it is an Ubuntu problem with JPG image. I have reduced my JFX app and tried to draw 2 images on JFX canvas: one is a JPG image and the other is a PNG image. And what I see is that PNG image is painted, but the JPG image gets lost. Here is the reduced app:

// JavaFX
import javafx.application.*;
import javafx.stage.*;
import javafx.scene.*;
import javafx.scene.layout.*;
import javafx.scene.control.*;
import javafx.geometry.*;
import javafx.scene.canvas.*;
import javafx.scene.paint.Color;
import javafx.scene.image.Image;
// FuzzyLogic
import fuzzylogic.*;
//
// FuzzyLogic Controlled Unmanned Aerial Chopper
// Joe Nartca (C)
//
public class MissingImage extends Application {
  public void start(Stage stage) {
    stage.setTitle("FuzzyLogic Controlled Drone -JoeNartca (C)-");
    try {
        scopter_jpg = new Image(new java.io.FileInputStream("scopter.jpg"));
        scopter_png = new Image(new java.io.FileInputStream("scopter.png"));
    } catch (Exception ex) {
        ex.printStackTrace();
        System.exit(0);
    }
    Canvas screen = new Canvas(580, 500);
    gc = screen.getGraphicsContext2D();
     gc = screen.getGraphicsContext2D();
    // fill canvas
    draw( );
    //
    VBox root = new VBox(10);
    root.setAlignment(Pos.CENTER);
    root.setPadding(new Insets(5,5,5,5));
    root.getChildren().addAll(screen);
    Scene scene = new Scene(root, 590, 590);
    // either inline styling or via file css.css
    stage.setScene(scene);
    stage.show();
  }
  // clean up before terminated
  public void stop() {
    Platform.exit();
    System.exit(0);
  }
    // paint the Canvas
  private void draw( ) {
    gc.setFill(Color.BLACK);
    gc.fillRect(0,0,580,580);
    gc.setFill(Color.RED);
    gc.drawImage(scopter_jpg, 290, 290); // Draw JPG image
    gc.drawImage(scopter_png, 320, 320); // Draw PNG image
    gc.fillOval(535, 480, 15, 15);
    gc.fillOval(510, 480, 15, 15);
    gc.setLineWidth(1);
    gc.setStroke(Color.YELLOW);
    gc.strokeText("FuzzyLogic Controlled Flying Drone - Joe Nartca (C) -", 124, 15);
  }
  private Image scopter_jpg, scopter_png;
  private GraphicsContext gc;
  public static void main(String... argv) {
      Application.launch();
  }
}

and the the jpg image the png image
