pdf - PDFBox - document is empty after loading -


i using apache pdfbox rendering thumbnails of pdf documents. therefore load pdf , use first page thumbnail. problem is, particular document, seems, not loaded correctly. other docs, works expected.

bytearrayinputstream = new bytearrayinputstream(pdfdata);

pddocument pdf = pddocument.load(is, true);

list<pdpage> pages = pdf.getdocumentcatalog().getallpages(); //pages empty here

the pdf file has 238 pages , around 6,5 mb of size.

assuming you're using 1.8.* version, please use non sequential parser:

pddocument pdf = pddocument.loadnonseq(is, null);

the non sequential parser successful in cases old parser fails, e.g. pdfs have had revisions (example). advantage no code needed "protected" pdfs encrypted empty password.
