Ok, here is the StackTrace:

Thats my method for creating the OffScreenCanvas3D:
// Background
Background background = new Background(1,1,1);
background.setApplicationBounds(mouseBounds);
BranchGroup backgroundBg = new BranchGroup();
backgroundBg.setCapability(BranchGroup.ALLOW_DETACH);
backgroundBg.addChild(background);
GraphicsConfiguration config =
SimpleUniverse.getPreferredConfiguration();
OffScreenCanvas3D offScreenCanvas3d = new
OffScreenCanvas3D(config,true);
// Set the off-screen size based on a scale factor times the
// on-screen size
//offScreenCanvas3d.setBackgroundNode(background);
Screen3D sOn = c.getScreen3D();
Screen3D sOff = offScreenCanvas3d.getScreen3D();
Dimension dim = sOn.getSize();
dim.width *= OFF_SCREEN_SCALE;
dim.height *= OFF_SCREEN_SCALE;
sOff.setSize(dim);
sOff.setPhysicalScreenWidth(sOn.getPhysicalScreenWidth() *
OFF_SCREEN_SCALE);
sOff.setPhysicalScreenHeight(sOn.getPhysicalScreenHeight() *
OFF_SCREEN_SCALE);
// attach the offscreen canvas to the view
offScreenCanvas3d.getGraphicsContext3D().setBackground(background);
offScreenCanvas3d.getGraphicsContext3D().clear();
u.getViewer().getView().addCanvas3D(offScreenCanvas3d);
Point loc = c.getLocationOnScreen();
offScreenCanvas3d.setOffScreenLocation(loc);
dim = c.getSize();
dim.width *= OFF_SCREEN_SCALE;
dim.height *= OFF_SCREEN_SCALE;
scene.addChild(backgroundBg);
offScreenCanvas3d.setBackgroundNode(background);
//u.getViewer().getView().addChild(backgroundBg);
//u.setJ3DThreadPriority( Thread.currentThread().getPriority() );
//offScreenCanvas3d.preRender(background);
//offScreenCanvas3d.getGraphicsContext3D().setBackground(background);
//offScreenCanvas3d.getGraphicsContext3D().clear();
bImage = offScreenCanvas3d.doRender(dim.width, dim.height);
backgroundBg.detach();
And here is the new version of OffScreenCanvas3D:
class OffScreenCanvas3D extends Canvas3D {
Background background;
OffScreenCanvas3D(GraphicsConfiguration graphicsConfiguration,
boolean offScreen) {
super(graphicsConfiguration, offScreen);
}
public void preRender() {
this.getGraphicsContext3D().setBackground(background);
this.getGraphicsContext3D().clear();
}
BufferedImage doRender(int width, int height) {
BufferedImage bImage =
new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
ImageComponent2D buffer =
new ImageComponent2D(ImageComponent.FORMAT_RGBA, bImage);
setOffScreenBuffer(buffer);
renderOffScreenBuffer();
waitForOffScreenRendering();
bImage = getOffScreenBuffer().getImage();
return bImage;
}
public void postSwap() {
// No-op since we always wait for off-screen rendering to complete
}
public void setBackgroundNode(Background background) {
this.background = background;
}
}

I am still using Java3D 1.2
Thanks for your help Desiree
