Adam Nichols updated PDFBOX-719:
--------------------------------
Attachment: PDFBOX-717.patch
The issue was that the "Last" bookmarks (according to the outline) was updated
to the node which was being appended. It didn't consider that there may be
"next" nodes in that bookmark.
For example, if we have three documents with bookmarks a, b, c; d, e, f; and x,
y, z (respectively), after merging the first two documents, the old code would
result in: a, b, c, d, e, f but the "Last" node would point to "d".
Consequently, when the next file is merged in, we get a, b, c, d, x, e, f. By
updating the "Last" pointer correctly, it resolves this issue.

>
> When multiple PDFs with bookmarks are merged, not all of the bookmarks are in
> the output and they are not in the expected order. The output will have all
> bookmarks from the first file, the first bookmark from all files, and then
> the bookmarks 2-n of file #2. Files 3 and above will only have the first
> bookmark copied over.
> The expected behavior is that all bookmarks for file 1 appear, followed by
> all bookmarks for files 2, then all bookmarks for file 3 and so on.
> Code to duplicate the problem:
> String inputFile = "C:\\US_Constitutional_Ammendments_bookmarked.pdf";
> String outputFile = "C:\\US_Constitutional_Ammendments_bookmarked3.pdf";
> PDFMergerUtility merger = new PDFMergerUtility();
> merger.setDestinationFileName(outputFile);
> merger.addSource(inputFile);
> merger.addSource(inputFile);
> merger.addSource(inputFile);
> merger.mergeDocuments();
