I have started work on testing my libraries against V2.0a5 and in particular looking at how well they work with the new OpenGL renderer. So in Eclipse I am trying to create a simple sketch that uses the OpenGL renderer.

Here is the sketch

1. import processing.core.PApplet;
2. 
   
3. public class OGLtest extends PApplet{
4.     public void setup(){
5.         size(200,200, OPENGL);
6.     }
7.  
8.     public void draw(){
9.     }
10. }

On the classpath I have added core.jar and opengl.jar from the V2.0a5 distrbution. The 'JRE System Library'  is jdk1.7.0_03 (32 bit version). The OS is Windows 7 64bit.

When I attempt to run the sketch I get the error stack trace shown below. The error in red below corresponds line 5 of the above source code.

If anyone has some ideas how I might solve this problem I would appriate hearing from you.
