Edi Weissmann commented on PDFBOX-4230:
---------------------------------------
I could have easily fixed this myself and opened a pull request, but it seemed
that pull requests via GitHub is not how the project accepts contributions. Let
me know if that's not the case, and I can happily provide a PR.
> NullpointerException in CmapSubtable
> ------------------------------------
>
> Key: PDFBOX-4230
> URL: https://issues.apache.org/jira/browse/PDFBOX-4230
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.9
> Reporter: Edi Weissmann
> Priority: Major
>
> I'm seeing a *NullpointerException* in *CmapSubtable.java* at line *601*
> {{java.lang.NullPointerException at
> org.apache.fontbox.ttf.CmapSubtable.getGlyphId(CmapSubtable.java:601)}}
>
> The cause seems to be that the *characterCodeToGlyphId* is not initialised by
> all code paths.
>
> The suggested fix would be to simply initialise the variable on declaration
> (line 48)
> {{private Map<Integer, Integer> characterCodeToGlyphId *= new
> HashMap<Integer, Integer>()*;}}
>
> Successfully tested this above suggested solution with a local build.
> Sorry, cannot share the PDF doc causing this.
