Blur works on png, won't work on jpg

[sage compass]

public class MedianBlur implements ImageBlur {

    public BufferedImage blur(BufferedImage image) {
        if (image == null) {
            throw new ImageNullException("Cannot blur null image");
        }

        int width = image.getWidth();
        int height = image.getHeight();
        BufferedImage blurredImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

        for (int y = 0; y < height; y++) {
            for (int x = 0; x < width; x++) {
                int[] reds = new int[9];
                int[] greens = new int[9];
                int[] blues = new int[9];
                int count = 0;

                for (int dy = -1; dy <= 1; dy++) {
                    for (int dx = -1; dx <= 1; dx++) {
                        int nx = x + dx;
                        int ny = y + dy;

                        if (nx >= 0 && nx < width && ny >= 0 && ny < height) {
                            int rgb = image.getRGB(nx, ny);
                            reds[count] = (rgb >> 16) & 0xFF;
                            greens[count] = (rgb >> 8) & 0xFF;
                            blues[count] = rgb & 0xFF;
                            count++;
                        }
                    }
                }

                Arrays.sort(reds);
                Arrays.sort(greens);
                Arrays.sort(blues);

                int medianRed = reds[4];
                int medianGreen = greens[4];
                int medianBlue = blues[4];

                int blurredPixel = (medianRed << 16) | (medianGreen << 8) | medianBlue;
                blurredImage.setRGB(x, y, blurredPixel);
            }
        }

        return blurredImage;
    }

Hello, guys I've tried to change:

BufferedImage blurredImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

But nothing seems to be happening

Detected code, here are some useful tools:

Formatted code

public class MedianBlur implements ImageBlur {
  public BufferedImage blur(BufferedImage image) {
    if (image == null ) {
      throw new ImageNullException("Cannot blur null image");
    }
    int width = image.getWidth();
    int height = image.getHeight();
    BufferedImage blurredImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
    for (int y = 0; y < height; y++) {
      for (int x = 0; x < width; x++) {
        int [] reds = new int [9] ;
        int [] greens = new int [9] ;
        int [] blues = new int [9] ;
        int count = 0;
        for (int dy =  - 1; dy <= 1; dy++) {
          for (int dx =  - 1; dx <= 1; dx++) {
            int nx = x + dx;
            int ny = y + dy;
            if (nx >= 0 && nx < width && ny >= 0 && ny < height) {
              int rgb = image.getRGB(nx, ny);
              reds[count]  = (rgb >> 16) & 0xFF;
              greens[count]  = (rgb >> 8) & 0xFF;
              blues[count]  = rgb & 0xFF;
              count++;
            }
          }
        }
        Arrays.sort(reds);
        Arrays.sort(greens);
        Arrays.sort(blues);
        int medianRed = reds[4] ;
        int medianGreen = greens[4] ;
        int medianBlue = blues[4] ;
        int blurredPixel = (medianRed << 16) | (medianGreen << 8) | medianBlue;
        blurredImage.setRGB(x, y, blurredPixel);
      }
    }
    return blurredImage;
  }
