> Key: PDFBOX-5485

> Project: PDFBox
> Issue Type: Bug
> Components: Writing
> Affects Versions: 3.0.0 PDFBox
> Environment: MacOS, but likely not OS specific.
> Reporter: Owen McGovern
> Priority: Major

> In a subset of PDFs I process, I cannot extract a range of PDF pages and write them out to a new PDF. ( As part of test code )
> Here's the Kotlin code I use
> {code:java}
> fun extractPages(documentName: String, fromPage: Int, toPage: Int) : Path {
> val pdfFile = Paths.get("data", "input", "PDFS", "${documentName}.pdf")
> val pdfPagesFile = Paths.get("data", "input", "PDFS", "${documentName}_Page_$fromPage-$toPage.pdf")
> val pdfDoc = org.apache.pdfbox.Loader.loadPDF(pdfFile.toFile())
> val pageExtractor = PageExtractor(pdfDoc, fromPage, toPage)
> val pdfPages = pageExtractor.extract()
> pdfPages.save(pdfPagesFile.toFile())
> return pdfPagesFile
> }{code}
> It doesn't occur in all PDFS... maybe 10-20% of the PDFs I use.

> As I mentioned, hits some PDFs, not all.
> I legally cannot share the original source PDFs but it looks like a recursive loop in writeCOSDictionary and writeObject in COSWriterObjectStream.
