问题
I'm trying to get a little bit into JOGL but it seems like I can't even get the program to start properly.
@SuppressWarnings("serial")
public class Test extends GLJPanel implements GLEventListener {
public static final void main(final String[] args) {
final long startTimeMillis = System.currentTimeMillis();
final GLProfile profile = GLProfile.get(GLProfile.GL4);
System.out.println("GLProfile#get -> " + (System.currentTimeMillis() - startTimeMillis));
final GLCapabilities capabilities = new GLCapabilities(profile);
final JFrame frame = new JFrame(Test.class.getName());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final Test t = new Test(capabilities);
frame.add(t);
frame.setVisible(true);
frame.pack();
frame.setLocationRelativeTo(null);
}
public Test(final GLCapabilities capabilities) {
super(capabilities);
super.setPreferredSize(new Dimension(960, 640));
super.addGLEventListener(this);
}
@Override
public final void init(final GLAutoDrawable drawable) {}
@Override
public final void dispose(final GLAutoDrawable drawable) {}
@Override
public final void display(final GLAutoDrawable drawable) {}
@Override
public final void reshape(final GLAutoDrawable drawable, final int x, final int y, final int width,
final int height) {}
}
As you can see there isn't much going on... The code works but it takes about 15 seconds to start. I ran it using -Xprof which resultet in the following output:

I already tested HelloTriangle which leads to the same result (except for that everything is working perfectly fine, constant FPS etc.).
What am I doing wrong? I'm on Windows 10 using Nvidia GTX by the way.
Unlike JOGL Jar runs fine on my development machine, but slowly on others? Even if they have better hardware, I don't have any problems with FPS/textures, only starting the program takes too long.
