PDFBOX-5795: avoid ArrayIndexOutOfBoundsException
> Crash for Softmask with incorrect backdrop color components
> -----------------------------------------------------------
>
> Key: PDFBOX-5795
> URL: https://issues.apache.org/jira/browse/PDFBOX-5795
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.31, 3.0.2 PDFBox
> Reporter: Daniel Persson
> Priority: Major
> Attachments: borsen-2065-20111030-1-p4.pdf, crashfix.patch
>
>
> This error occured in our production of an old archive. None of the files
> crashed in any other viewer (Chrome, Adobe, Firefox, Poppler a.s.o).
>
> I've read up on the subject in the 1.7 specification, and it seems like
> PDFBox is following the specification, but not being able to open these files
> seems a bit too strict.
>
> The easiest way to reproduce is just to open the attached file with the
> debugger.
> {code:java}
> java -jar debugger-app-4.0.0-SNAPSHOT.jar borsen-2065-20111030-1-p4.pdf {code}
> The application will crash with this exception:
> {code:java}
> Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds
> for length 1

> My solution, added as a patch, is to add a fallback to the colorspace
> available in the graphical context. This is working for the files I've tried
> so far.
