Exception"Type system" on loading PPTX (Java)

Aspose.Slides Product Family

We encountered a PPTX file that Aspose.Slides Java 18.2.1-jdk16 fails to load, failing with exception:

Exception in thread "main" class com.aspose.slides.pa5e0ff62.pbdb106a0.cs: Exception of type 
System.Exception was thrown.

I eventually found that the culprit was one label in a pie chart. A problem-reproducing file can be generated using PowerPoint 2016 by doing:

  • create new file
  • add blank slide
  • add a pie chart
  • add data callout labels
  • resize a label and move it’s callout pointer
    ** these last two modifications need to be done in that order and without closing PowerPoint in between
