下面的代码在我的桌面上运行得很好：

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);

然而，当我在我的服务器上运行这段代码时（openjdk在Docker容器内的Linux alpine上运行），它失败了，并出现以下错误：

java -version（在我的服务器上）给出：

openjdk version "1.8.0_77-internal"
OpenJDK Runtime Environment (build 1.8.0_77-internal-alpine-r0-b03)
OpenJDK 64-Bit Server VM (build 25.77-b03, mixed mode)

我搜索了awt libs，可以在这里找到：

/usr/lib/jvm/java-1.8-openjdk/jre/lib/amd64/libawt_headless.so
/usr/lib/jvm/java-1.8-openjdk/jre/lib/amd64/libawt.so
