LynX commented on PDFBOX-720:
-----------------------------
Dear Adam,
Unfortunately I was not able to reproduce this problem on my Debian. I've tried
different PDBbox distrs (1.1.0, 1.2.0, 1.6.0) with different JVMs (same Sun JDK
1.5.0_06 as your were using and OpenJDK 1.6). In all cases I received "Document
outline was not null" message. As David stated before it is "dependant on the
implementation of HashMap on the host system" so I guess my hosts system is not
appropriate for this :).
Are you still able to reproduce this problem on your system? If yes could you
please try apply the patch from PDFBOX-569. I believe it may fix the problem.
Regards,
LX

> Red Hat Linux, 2.6.9-67.ELsmp kernel, Java 1.5.0_06, PDFBox HEAD tag

> 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.
