I have uploadet the PDF here: https://we.tl/t-lQusIcUiRM
I have testet with both version 2.0.13 and 2.0.15 of PDFBox, and I have run the test on a machine with 16 GB of ram, where I allowed JVM to use 14 GB using the -Xmx14g parameter. I took a heap dump using JVisualVM when it used approx 12 GB of memory and I can see that 98,3% of the size is taken up by int[]’s. When I dig into those they come from featuredIndices in GlyphSubstitutionTable$LangSysTable -> langSysTable in GlyphSubstitutionTable$LangSysRecord -> GlyphSubStitutionTable$LangSysRecord[]. I should also note that I run our app in a Docker container, like this: docker run -d \ -p 8080:8080 \ -v /home/ec2-user/locate/build:/usr/build \ --name=locate \ openjdk:8 \ java -Xmx14g -Dserver.port=8080 -Dspring.profiles.active=prod -Djdk.tls.useExtendedMasterSecret=false -jar /usr/build/project-web-1.3.0.war Thanks a lot in advance!
