Could Not Save Slides to PDF in Java 17. Error: InvocationTargetException


I am using Aspose.total with Developer OEM license.

  • With Aspose slides, I am trying to convert a PPTX file to PDF as follows :
 com.aspose.slides.LoadOptions loadOptions = new com.aspose.slides.LoadOptions();
 Presentation pres = new Presentation(GZIPInputStreamObject, loadOptions);
 pres.save(fileOutputStream, com.aspose.slides.SaveFormat.Pdf);
  • Previously, I am working with [java.version - 1.8.0_231]
    In [Java - 1.8], these PPTX to PDF conversion works as expected.
  • I am using the latest version of Aspose slides [22.7]
  • To check the performance in updated Java versions, I changed [Java.version - 17]
  • I’ve tested PPTX to PDF conversion with Aspose.Slides 22.7 and Java 17, it works fine in local Windows PC.

We are facing this issue only in server.

Operating System: Red Hat Enterprise Linux Server 7.9 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.9:GA:server
Kernel: Linux 3.10.0-1160.49.1.el7.x86_64
Architecture: x86-64

JAVA Version : 17.0.4 (openjdk-17)

  • Now, If I try to convert any PPTX file to PDF in server, the last line [pres.save()] throws the below error :

[ERROR MSG] Handler dispatch failed; nested exception is java.lang.InternalError: java.lang.reflect.InvocationTargetException
[ERROR CAUSE] java.lang.InternalError: java.lang.reflect.InvocationTargetException

Do I need to add any other configuration for later Java versions (JDK-17) ?

Our developers have investigated the case. As you can see, the main problem here is “Cannot load from short array because “sun.awt.FontConfiguration.head” is null”. This issue is related to the Linux configuration and can be resolved with the following commands:
