Nehe lesson problem

[jorrit5477]

Hello,

I have just started with opengl and stumbled on this library, so I am working my way through the Nehe tutorials and the ports made for lwjgl (many thanks by the way! Both for lwjgl and for the tuts.)
But in the ports I got a problem. In lesson 6 a texture is loaded using awt/swing. Everything runs fine in windowed mode, but when I run it in fullscreen and I close the app, I get the following error:

D:\GameDevel\Java\NeHeGLLessons\Lesson06\Lesson06>java Lesson06 fullscreen
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
       at sun.awt.Win32GraphicsEnvironment.displayChanged(Unknown Source)

       at java.awt.EventDispatchThread.run(Unknown Source)

Since I am not a Java guru I am wondering why this happenes and what (though it seems to me the awt thread is not properly closed)? If I implement the code for getting the image from http://lwjgl.org/forum/viewtopic.php?t=640&highlight=nehe+texture instead of

Image image = (new javax.swing.ImageIcon(path)).getImage();

, so not using swing everything goes fine.
I am using JDK1.5.0 with lwjgl0.93 on an Windows XP machine.

Hope that someone can help me out on this one.

Regards,
Jorrit

Well, if you're using my tutorials on www.shakebox.org which seems to be the case, it's a weird bug that come with Java 1.5. I must update the tutorials that use this texture loading method...

If you want another way to load textures, look at the DevIL demo

Thanks for the reply. I have to admit I haven't tried to compile it with an older jsdk (I only have 1.4.2_05 and 1.5.0 here), but I'll have a check.
The ports I use are from Mark Bernard, but I'll have a look at the ones on your site. The seem to be quite promising to me, but still have a long way to go...

Just did a check with 1.4.2_05 and no problem... have to figure out why this happens in 1.5.0...
