On a machine with 4GB RAM and RHEL 9.2 OS. We have out webapp configured with -Xms1024m configuration for JVM. When we are processing PPT/PPTX files we encountered sudden memory usage shoot up which inturn results into HeapOutOfMemory problem and Server crashes.
This is even observed on basic PPT/PPTX files with size less than 200kB.
We tried the same scenario on system with 4GB RAM and RHEL 8.8 OS and issue is reproducible on same.
What are we doing with presentation files?
→ We are getting the document properties, setting some custom properties, and saving the files. The Heap Space issue is observed while saving the files.
We are facing this issue only on linux systems and not on Windows System.
We have tried Aspose-slides for java 23.12 and 24.1 and we have observed the issue with both.
Also we see following WARNING messages in our Web Server logs:
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.aspose.slides.internal.ox.d0 (file:/opt/seclore/decryption-server/decryption-server/WEB-INF/lib/aspose-slides-24.1-jdk16.jar) to method sun.font.FontUtilities.getFont2D(java.awt.Font)
