# Spurious comma appears when combining hyperref pdfa with hyperxmp

I'm authoring a document using LuaLatex / TexLive v. 6:2016-33.20160520 on Fedora 25. When I use both the hyperref and hyperxmp packages a strange comma appears at the very bottom right of the page (to the right of the page number), after compiling the document twice in a row.

Is this a bug? Am I doing something wrong?

Simple code to reproduce the problem:

\documentclass[letterpaper,12pt]{article}
\usepackage[pdfa]{hyperref}
\usepackage{hyperxmp}
\begin{document}
Text.
\end{document}


• Doesn't happen to me. Perhaps you need an update? – Moriambar Apr 19 '17 at 20:57
• Did not happen for me. TeXlive2016 Ubuntu, everything current. – user103221 Apr 19 '17 at 21:08
• I see it, and also with pdflatex but in another place. – Ulrike Fischer Apr 19 '17 at 21:14
• Now I see it, when compiled with pdflatex. Comma appears to right of Text, about the distance of a paragraph indent. But I still do not see it anywhere on the page, with lualatex. – user103221 Apr 19 '17 at 21:29
• I think you can avoid it by loading hyperxmp before hyperref and by adding at least one pdf info, like e.g pdfauthor. – Ulrike Fischer Apr 19 '17 at 21:45

The slightly different behavior observed among those who commented, suggests that the pdfx package (or an included package) has had a code modification somewhere along the line.
