Attachment: page_label.pdf
> ArrayIndexOutOfBoundsException with extracting labels from malformed document

> Key: PDFBOX-900
> URL: https://issues.apache.org/jira/browse/PDFBOX-900
> Project: PDFBox
> Issue Type: Bug
> Reporter: Kevin Jackson
> Attachments: page_label.pdf

>
> This document opens fine in Adobe Reader but inside there is a negative page
> label offset. This results in an ArrayIndexOutOfBoundsException in
> getLabelsByPageIndices() in PDFBox
> My patch is to ignore that page label.
