Hi folks,

There is a recurring problem with PDF files produced by either pdftex or
luatex in France.
Whenever PhD thesis documents are submitted to the French national
archives, they have
to be validated by some automated process which relies on pdftk
(apparently).
And files compiled by pdftex/luatex are rejected.

The problem is described here :

French pdftex/luatex users will have an eternal gratitude to whoever will
make this work :-)

As far as I know luatex (and pdftex) produce valid pdf files. Of course one can add all kind of crap to a pdf file liek invalid objects and so but that is not our responsibility.

Now, to the file:

https://github.com/dbitouze/yathesis/blob/master/doc/latex/yathesis/master-slaves-files-sample/these.pdf?raw=true

Acrobat preflight says that there should be an indirect object in an annotation (normally I'd expect a viewer not to bark on it and acrobat itself handles it ok). Those annotations are probably made by some macro package and one should check that code.

But ... you mention "pdftex or luatex" but this file is not produced by
any of those engines: it's made by xdvipdfmx which is something xetex.

So we're off the hook.
