CSS reference specifies that image border is drawn on top of the stroke border (See Region section). JavaFX does it in the reverse order.

"Each Region consists of several layers, painted from bottom to top, in this order:

background fills
background images
contents
border strokes
border images"

                .scene(
                    SceneBuilder.create()
                        .root(BorderPaneBuilder.create()
                            .style("-fx-border-image-source: url(\"file:///D:/JavaFX/repos/jfx/apps/internal/EmbeddedMediaPlayer/src/embeddedmediaplayer/images/popupWindow.png\");"
                                + " -fx-border-image-width: 83 47 45 46;"
                                + " -fx-border-color: red;"
                                + " -fx-border-width: 83 47 45 46;"

                .applyTo(stage);
        stage.show();
