I don't know if I should send the bug report here.
I download the latest itext and itextsharp and find a bug. If I burst a PDF file into pages and merge them into one PDF file again using pdfsam (
http://sourceforge.net/projects/pdfsam), getPageContent will not return the correct content of the remerged PDF file, while ExtractText from PDFbox(
www.pdfbox.org) can extract all the text correctly from the same PDF file.
