Andreas Lehmkühler commented on PDFBOX-1922:
--------------------------------------------

As far as I can remember it, I wasn't aware of the fact that a pdf may have to 
versions (header + trailer). In the hindsight the change wasn't that good. I 
agree with [~msahyoun], we have to overhaul the get/setVersion methods. Both 
must take both possible values into account following the pdf spec.

> On older pdf files, the NonSequentialParser returns a different PDFVersion 
> than the traditional parser via the call: 
> document.getDocument().getVersion().  
> I think this is because NonSequentialParser is not reading the header but 
> relying on the default 1.4 if no version is found in the trailer.
> Many apologies if this is a duplicate.  I feel like I've seen this issue 
> elsewhere, but I can't track it down.
