Tilman Hausherr commented on PDFBOX-3041:
-----------------------------------------
[~torakiki] is the code change what you had in mind? I don't have a test file
so I created one. Sadly it isn't really testable because we have so many repair
mechanisms, i.e. it also opens without the change.
> Wrong default type in Xref stream W0 element
> --------------------------------------------
>
> Key: PDFBOX-3041
> URL: https://issues.apache.org/jira/browse/PDFBOX-3041
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 2.0.0
> Reporter: Andrea Vacondio
> Attachments: PDFA-XRefUncompressed-W0_2_0.pdf
>
>
> According to the spec, when parsing a cross reference stream and the W array
> has a 0 as first element (something like [0 4 1]). this should happen:
> "If the first element is zero, the type field shall not be present, and shall
> default to type 1".
> So entries read in this scenario should have type 1, in use.
> From org.apache.pdfbox.pdfparser.PDFXrefStreamParser::parse line 115-123 the
> default type assigned by PDFBox in this scenario is 0, free.
