We met the same error in Aspose.Slides compatability with Open JDK 11 (Java) - #10 by mudassir.fayyaz. The version we are using is slide 21.6, and I notice that com.sun.imageio.plugins.jpeg.JPEGImageReader is not deprecated now. May I get more information on this?
@adayao,
Aspose.Slides for Java uses JPEGImageReader
for better performance if it is available. Those warnings have been added to JDK since version 9. You can use the following JVM option to suppress these messages: --add-opens
