Please attach your file into that issue https://issues.apache.org/jira/browse/PDFBOX-4952
If you can't attach the file (happens sometimes), then upload it to a sharehoster and post the link there.
(But make sure it isn't related to you running pdfbox in some tiny system, i.e. try increasing stack size first)

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
