Andreas Lehmkühler commented on PDFBOX-737:
-------------------------------------------

Before we include your patch I've one question: Isn't your document well structered or do we have a parser issue? Following the pdf reference the Kids entry in the dictionary is required and not optional. Does your document contain such an entry or is it missing?

> getAllKids(List result, COSDictionary page, boolean recurse) throws a NullPointerException when page.getDictionaryObject( COSName.KIDS ) returns null.  I have a PDF where this actually happens but I can not provide it due to the confidential information it contains.  I confirmed that once I added the null check that the code worked as expected (the documents I was merging were visible, the page count was correct, etc.).  Patch will be attached momentarily.
