> 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
