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;
    }
