Hi PDFBox Team, We are facing a problem with the larger PDF files generated by PDFBox. When looking into the 3.0.0-RC1 release notes, the following item is mentioned "[PDFBOX-4952] - PDF compression - object stream creation" .
When I tried with 3.0.0.RC1, compression was happening and the file size was small compared to the 2.x version. But when I tried to export a medium sized file of 1500 pages then saving PDDcouemnt.save is failing with a stack overflow error. Seems like the entire object tree is loaded into the stack recursively before writing into the file. *"Caused by: java.lang.StackOverflowError* * at java.util.HashMap.hash(HashMap.java:339) at
