Producer address points to net-lowagie.com instead of itextpdf.sf.net and/or lowagie.com
ITEXT_VERSION in java/pdftk/com/lowagie/text/Document.java is hardcoded to "itext-paulo-155 (itextpdf.sf.net-lowagie.com)" and the string appears as the Producer in joined PDFs Note that the last string points to a single address of itextpdf . sf . net-lowagie . com instead of pointing to the 2 different addresses itextpdf . sf . net and lowagie . com
Unfortunately somebody had the idea of registering net-lowagie.com, so people who clicks at the Producer address get mislead to the wrong one.
Maybe you could consider to split the addresses with a space or similar HTH Pere
