Tilman Hausherr commented on PDFBOX-2804:
-----------------------------------------
Maybe there's a difference between /Info entry missing, and /Info entry exists
but is null? I tried to change the code so that it checks for missing XMP
entries if dico.getTitle() returns null, but then other tests fail, e.g.
good0000.pdf...good013.pdf of the bavaria tests, which have no /Info entry.
