---- Reported by esalbert 2008-04-15 16:28:20 ---- When trying to compile a simple test program (just draws a triangle), <pre> package test; import java.awt.BorderLayout; import javax.media.opengl.*; import javax.swing.*; public class SimpleTest implements GLEventListener { public SimpleTest() { super(); } public void init(GLAutoDrawable drw) { drw.setGL(new DebugGL(drw.getGL())); GL gl = drw.getGL(); gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT); gl.glLoadIdentity(); } // init public void display(GLAutoDrawable drw) { GL gl = drw.getGL(); gl.glColor3f(1.0F, 0.4F, 0.0F); gl.glBegin(GL.GL_TRIANGLES); gl.glVertex3f(0.0F, 0.0F, 0.0F); gl.glVertex3f(1.0F, 0.0F, 0.0F); gl.glVertex3f(1.0F, 1.0F, 0.0F); gl.glEnd(); } // display public void reshape(GLAutoDrawable drw, int x, int y, int wid, int hite) { } // reshape public void displayChanged(GLAutoDrawable drw, boolean modeCh, boolean devCh) { } // displayChanged public static void main(String[] argv) { GLCapabilities glCaps = new GLCapabilities(); // This line fails with the current (1.1.1.1-rc8 - February 22) build, // but works if GLCanvas is changed to GLJPanel.

Using the 1.1.0 release versions of the libraries, it worked either way. Please let me know if I need to provide any more information. The machine is a Dell Precision PWS390 computer running Windows XP Professional with a Core 2 CPU and 2 GB of RAM. I did set the "-Dsun.java2d.noddraw=true" flag. Thank you for considering this matter.
