-----------------------------------------
Thanks for reporting this; yes I'd like to have the file, to add it to my test
set. Please do also give feedback whether the problem has been solved or if
there are new problems now.
> NullPointerException - missing glyph description
> ------------------------------------------------

> Key: PDFBOX-3511
> URL: https://issues.apache.org/jira/browse/PDFBOX-3511
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.0, 2.0.1, 2.0.2, 2.0.3
> Reporter: Daniel Persson
> Priority: Minor
>
> Hi Team.
> We process many PDF documents every day and today we ran into a file that we
> couldn't create an image to. For some reason it has glyphs that didn't have
> any glyph description.
> In GlyfCompositeDescript there is atleast two functions (Line 258, 271) that
> fetch an GlyphDescription from a map like this:
> GlyphDescription gd = descriptions.get(c.getGlyphIndex());
> Then the functions use the description without a null check which results in
> an NullPointer exception.
> Exception in thread "main" java.lang.NullPointerException
