I use a 32-bit jdk on a Win64 machine. I got the error with NEWT and AWT.
Without setSampleBuffers(true) the Shader doesn't compile and the variable logLength[0] returns zero.
public class GLCapabilitiesBug implements GLEventListener
{
/**
* @param args
*/
public static void main(String[] args)
{
new GLCapabilitiesBug();
}
private GLWindow window;
public GLCapabilitiesBug()
{
this.window = GLWindow.create(this.getGLCapabilities());
this.window.addGLEventListener(this);
this.window.setVisible(true);
while(true)
{
window.display();
}
}
protected GLCapabilities getGLCapabilities()
{
GLProfile glp = GLProfile.get("GL2GL3");
GLCapabilities caps = new GLCapabilities(glp);
caps.setStencilBits(8);
//caps.setSampleBuffers(true);
return caps;
}
