Question

我正在测试具有多个不同Java功能的graalVM本机映像限制。我写了一个小程序来执行canny边缘检测，并使用javax.ImageIO类将其加载到图像中。代码可以编译为本地映像，但是在将代码作为本地映像运行时出现以下运行时错误：

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.sun.imageio.plugins.jpeg.JPEGImageReader.initJPEGImageReader()J [symbol: Java_com_sun_imageio_plugins_jpeg_JPEGImageReader_initJPEGImageReader or Java_com_sun_imageio_plugins_jpeg_JPEGImageReader_initJPEGImageReader__]

    at javax.imageio.ImageIO.read(ImageIO.java:1463)
    at javax.imageio.ImageIO.read(ImageIO.java:1315)
    at Main.main(Main.java:32)

由以下代码行引起：

        File file = new File(args[0]);

        BufferedImage image = ImageIO.read(file);

我尝试在jni-config.json文件中指定JpegImageReader：

[
  {
    "name" : "com.sun.imageio.plugins.jpeg.JPEGImageReader",
    "allDeclaredConstructors" : true,
    "allPublicConstructors" : true,
    "allDeclaredMethods" : true,
    "allPublicMethods" : true
  }
]

但是，我仍然收到与以前相同的错误。有谁知道graalvm本机映像是否可以支持ImageIO，为什么不支持ImageIO？

graalVM本机图像是否支持Javax.ImageIO？
