Tilman Hausherr commented on PDFBOX-720:
----------------------------------------

Is this still an issue when using the non sequential parser?

> Inconsistency in parsing PDFs between Windows and Linux

> Run this same code using the same PDF and you'll get different results on 
> Linux than on Windows.  Regardless of which one you consider "correct", it 
> should be consistent.
> doc = PDDocument.load(inputFile);
> PDDocumentOutline outline = doc.getDocumentCatalog().getDocumentOutline();
> if(outline == null)
>     System.out.println("Document outline was null");
> else
>     System.out.println("Document outline was not null");
> Some interesting notes about this PDF: Seems that Acrobat Distiller 8.1.0 
> basically just concatenated two PDFs into one.  There are two trailers, they 
> both refer to object "1600 0" as the root.  1600 0 appears multiple times, 
> one time it doesn't have "Outlines" in the dictionary, the other time it has 
> "Outlines 1667 0".  Windows picks up the latter and shows the outline 
> correctly.  Linux picks up the former and thus returns null for the outline.  
> I tried debugging through PDFParser and BaseParser, but I'm not really sure 
> how that code works and I quickly got lost.
