  1. Unable To Encode Buffered Image

    Set -Djava.awt.headless=true did not help in my case. I had to modify the Java code to make it work. Two key changes: 1: do not use Graphics object in ImageGenerator.java 2: do not use BasicEncoder.encode(BufferedImage bufferedImage, OutputStream outputStream, float quality, String format) method, use ImageIO.write(bufferedImage, format, outputStream) instead
