If this is the only diff between the Java's involved here, it is interesting that it is sufficient to switch photo pair distances from Group 2 to Group 3 in the interpretation of the histograms as coordinates in Poincare spherical space.

Example RGB diff between OpenJDK and Oracle; 673/58903 pixels differ, often by 1, but also like this:

43480c43480

< -9876933

---

> -9942469

43491c43491

< -9876931

> -9942467

--------

    BufferedImage buffered = ImageIO.read("img2112a.jpg");

    try {
        PrintStream out = new PrintStream(new File("pixels_2112"));
        for (int i=0; i<buffered.getWidth(); i++) {
            for (int j=0; j<buffered.getHeight(); j++) {
                out.println("" + buffered.getRGB(i, j));
            }

        }
        out.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
