以下代码在我的桌面上运行良好:
BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
Graphics g = image.getGraphics();
g.setFont(new Font("SansSerif", Font.BOLD, 18));
Graphics2D graphics = (Graphics2D) g;
graphics.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
graphics.drawString(s, 5, 20);

但是,当我在我的服务器上运行此代码(在 Docker 容器内的 linux alpine 上运行的 openjdk)时,它失败并显示以下错误:
