I am using Processing-0154 on latest Java 6 (1.6.0_10) and Linux(Ubuntu
intrepid) IN ECLIPSE

I am getting a launch error when I use the OPENGL video mode. It looks like
a loaded class is trying to reference a previously loaded class (in a
previous classloader). where the access method is protected. I noticed the
access for the bindTexture method changed from public to protected recently
- this may have something to do with it.

When running this code as an applet in eclipse the below error occurs.
import processing.core.PApplet;

public class TestVid extends PApplet {
public void setup() {
size(800,600, OPENGL);
}
public void draw() { }
}

Exception in thread "Animation Thread" java.lang.VerifyError: (class:
processing/opengl/PGraphicsOpenGL, method: bindTexture signature:
(Lprocessing/core/PImage;)V) Bad access to protected data

you're mixing different versions of core.jar in your eclipse setup.

Just to document this, i had changed the core.jar reference to use the new
processing-0154 lib but hadn't replaced the opengl.jar reference (to
processing-0148) to use the new one.

yup, welcome to Java development.
