I think you can wait for GVT listener specially rendererComplete. Hope
it solve your problem.

It maybe because the viewbox or transform stuff. Try to calculate the
bounds by applying the transform of graphicsNode.getGlobalTransform()
eg: 
Shape shape = (Shape)graphicsNode.getBounds();
AffineTransform at = graphicsNode.getGlobalTransform()
shape = at.createTransformedShape(shape);
Rectangle bounds = shape.getBounds();
