William Palmer created PDFBOX-1759:
--------------------------------------
Summary: NullPointerException when loading/saving a PDF
Key: PDFBOX-1759
URL: https://issues.apache.org/jira/browse/PDFBOX-1759
Project: PDFBox
Issue Type: Bug
Components: Parsing
Affects Versions: 1.8.2
Environment: Ubuntu Linux & Windows 7 (both JDK6)
Reporter: William Palmer
Priority: Minor
Loading and saving a PDF causes a NullPointerException:
java.lang.NullPointerException
at org.apache.pdfbox.pdmodel.PDPageNode.updateCount(PDPageNode.java:98)
at org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:1319)
at org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:1305)
Files that cause this exception:
https://github.com/openplanets/format-corpus/blob/master/pdfCabinetOfHorrors/encryption_openpassword.pdf
https://github.com/openplanets/format-corpus/blob/master/pdfCabinetOfHorrors/encryption_notextaccess.pdf
https://github.com/openplanets/format-corpus/blob/master/pdfCabinetOfHorrors/encryption_noprinting.pdf
https://github.com/openplanets/format-corpus/blob/master/pdfCabinetOfHorrors/encryption_nocopy.pdf
Code to reproduce:
PDFParser parser = new PDFParser(new FileInputStream("file"));
parser.parse();
File temp = File.createTempFile("temp-", ".pdf");
parser.getPDDocument().save(temp);
parser.getDocument().close();
I imagine the exception is thrown because the files have restrictions within
them but I would not expect to get a NullPointerException if that is the case.
