Re: Lost xref table on two PDF merge
Hi, which version of PDFBox are you using? Did you save the merged pdf before you try to fix the signature? The resulting pdf should have a valid xref table.

When I merge these PDF first and then try to search for corrupted signature I will get nothing from document.getDocument().getObjectsByType(COSName.SIG) since xref table of second PDF is replaced with the one from first one. I can get around it in my code but is there a possibility to keep xref table from both PDFs after merge?

Re: Blank page generation issue - Unknown code in Huffman RLE stream
2.0.19 is 4 years old, why are you using it? Please retry with 2.0.31. I tried and your file works, despite that it is broken.
