我正在尝试在Raspberry Pi2上编写一个简单的FX8图像显示程序，只有64MB的GPU内存 . 这会导致com.sun.prism.impl.BaseGraphics.drawTexture尝试渲染ImageView时出现NullPointer异常 . 这是打包的Oracle JDK8（build 1.8.0-b132） .

我在Pi stackexchange上被告知128MB是使用OpenGL功能的最小GPU内存，这似乎并不合理......但我认为我没有做任何花哨的事情需要OpenGL .

问题

我是JavaFX和Pi的新手，所以也许我走向了错误的方向 . 我正在使用Rasbian / X11，但我并不依赖它 . JavaFX8是否有一种机制可以让我在不使用OpenGL的情况下显示全屏图像？

MCVE：

我的最小演示非常简单：一个持有ImageView的AnchorView，displaying a 29kB PNG (1847x1080) .

package sample;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception
    {
        Image image = new Image("/Sponsor.png");
        ImageView imageview = new ImageView(image);
        AnchorPane root = new AnchorPane(imageview);
        Scene scene = new Scene(root, 400, 275);
        primaryStage.setScene(scene);
        imageview.setFitHeight(scene.getHeight());
        imageview.setFitWidth(scene.getWidth());
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
