尝试使用 Swing 和 JOGL 创建 window 的索引越界异常

Question

此代码只是用来显示 window 并设置其背景颜色：

public class Code extends JFrame implements GLEventListener {

    private GLCanvas myCanvas;

    public Code() {
        setTitle("Chapter2 - program1");
        setSize(800, 600);
        setLocation(400, 400);
        myCanvas = new GLCanvas();
        myCanvas.addGLEventListener(this);
        this.add(myCanvas);
        setVisible(true);
    }

    public void display(GLAutoDrawable drawable)
    {  GL4 gl = (GL4) GLContext.getCurrentGL();
        float[] bkg = { 1.0f, 0.0f, 0.0f, 1.0f };
        FloatBuffer bkgBuffer = Buffers.newDirectFloatBuffer(bkg);
        gl.glClearBufferfv(GL_COLOR, 0, bkgBuffer);
    }

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

    public void init(GLAutoDrawable drawable) { }
    public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) { }
    public void dispose(GLAutoDrawable drawable) { }

我得到的错误是这个：

我正在使用 java 8 和 sdk 17.0

找到这个：https://forum.jogamp.org/Crash-in-WindowsAWTWGLGraphicsConfigurationFactory-td4040703.html

Source from https://github.com/JogAmp/jogl/blob/master/src/jogl/classes/jogamp/opengl/windows/wgl/awt/WindowsAWTWGLGraphicsConfigurationFactory.java

源代码： 170：如果（0 > gcIdx）{ 171：选择GC =配置[gcIdx]；在一个上使用负索引数组总是会崩溃。

看来您也在使用负索引。

Answer 2

我终于找到了解决办法。我将我的 OpenJDK 版本更改为 11。它运行正常，但我不知道为什么。我不知道错误出现在哪个版本，11 之前的版本似乎可以工作。

编辑它应该在最新版本的 JOGL 中得到修复，因此您可能需要更新 .jar
