Description

Strictly speaking not even a bug, merely a nuisance, but it might indicate an underlying issue in version handling.

When generating a HelloWorld.pdf as in this stack overflow question, the resulting PDF starts like this:

%PDF-1.6
%öäüß
1 0 obj
<<
/Type /Catalog
/Version /1.4
/Pages 2 0 R
>> 

This Version value 1.4 makes no sense in a freshly created PDF with a %PDF-1.6 header and will be ignored by a standard conform PDF processor.

So it should not be there to start with.

Its presence might indicate, though, that internally PDFBox has a non-appropriate idea which PDF version it is wanting to communicate to a processor. If so, that should also be cleared up.
