STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
this is the method i use

it happens when contrast is set ot true



public static BufferedImage makeGrayscale(BufferedImage _image)
{
int width = _image.getWidth(), height = _image.getHeight();
BufferedImage newImage = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY);

for (int i = 0; i < width; i++)
{
for (int j = 0; j < height; j++)
{
Color rgb = new Color(_image.getRGB(i, j));

for (int k = 0; k < brightness; k++)
rgb = rgb.brighter();

for (int k = 0; k < darkness; k++)
rgb = rgb.darker();

if (contrast)
{
BufferedImage __image = new BufferedImage(_image.getWidth(), _image.getHeight(), BufferedImage.TYPE_BYTE_GRAY);
float factor = 1.4f;

RescaleOp op = new RescaleOp(factor, 10f, null);
op.filter(_image, __image);
_image = __image;
}
int gray = (rgb.getRed() + rgb.getBlue() + rgb.getGreen()) / 3;

Color grayCol = new Color(gray, gray, gray);
newImage.setRGB(i, j, grayCol.getRGB());
}
}

return newImage;
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
no crash
ACTUAL -
crash -> hs_log file

REPRODUCIBILITY :
This bug can be reproduced always.
