Description

I use PDFBox to split hundreds of PDFs per day, generally, everything works flawlessly but I just received a PDF that generates an infinite loop when I try to split it.

 

I used this Java code to reproduce it using PDFBox 3.0.2 (haven't tried other versions):

private static void splitPdf(File fileToSplit) {
  try (PDDocument document = Loader.loadPDF(fileToSplit)) {
    int documentPages = document.getNumberOfPages();
    Splitter splitter = new Splitter();
    List<PDDocument> Pages = splitter.split(document);
    Iterator<PDDocument> iterator = Pages.listIterator();
    while (iterator.hasNext()) {
      PDDocument pd = iterator.next();
      pd.save(fileToSplit.getName() + "-" + Pages.indexOf(pd) + ".pdf");
      pd.close();
    }
  } catch (IOException e) {
    throw new RuntimeException(e);
  }
} 

The PDF file is attached to the issue
