What version are you using? We recently fixed a bug with merge.

I use pdfbox to merge PDF files but we find that many files from scanners or files generated from AutoCAD do not merge properly (they are either blank or missing fonts). However, when we open and save the file in a native reader such as Adobe Reader (Windows) or Preview in Mac, and then merge again, the merge works fine! Is there a workaround for this in PDFBox? Thanks, Marc
