Hi, With some of our PDFs I get two different errors: 1: java.lang.NullPointerException at org.apache.pdfbox.multipdf.Splitter.cloneStructureTree(Splitter.java:238) at org.apache.pdfbox.multipdf.Splitter.split(Splitter.java:145) at org.apache.pdfbox.tools.PDFSplit.call(PDFSplit.java:133) at org.apache.pdfbox.tools.PDFSplit.call(PDFSplit.java:41) at picocli.CommandLine.executeUserObject(CommandLine.java:2031)
This appears to be related to your change in rev 1925636 (PDFBOX-6009: get ParentTreeNextKey from tree). I note that with the commit before this change, the splitter runs and generates files, but I've not yet verified the accuracy of the structure tree. This appears to happen on files whose /K have no /Pg element 2 Exception in thread "main" java.lang.StackOverflowError at java.base/java.lang.StringCoding.encodeUTF8(StringCoding.java:909) at java.base/java.lang.StringCoding.encode(StringCoding.java:449) at java.base/java.lang.String.getBytes(String.java:964) at org.apache.pdfbox.cos.COSName.writePDF(COSName.java:778) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSName(COSWriterObjectStream.java:308) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:232) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:352) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:240) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:354) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:240) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSArray(COSWriterObjectStream.java:329) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:236) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:354) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:240) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:354) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:240) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSArray(COSWriterObjectStream.java:329) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:236) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:354) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:240) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSArray(COSWriterObjectStream.java:329) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:236) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:354) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeObject(COSWriterObjectStream.java:240) at org.apache.pdfbox.pdfwriter.compress.COSWriterObjectStream.writeCOSDictionary(COSWriterObjectStream.java:354) ... continues I also get this stack overflow on one of the sample files that I successfully tested on Friday, so it's possible that a change since then has caused this. This appears to happen on files whose /K do have a /Pg (on files with no /Pg I get the NPE first) I'm currently verifying if we can privately share these documents with you. Please let me know if it would be useful for debugging. I have an account on apache jira, please let me know if you'd prefer to continue there, or if it's OK to use the mailing list.
