PDFBOX-3511: avoid NullPointerException
> 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
