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:


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.
