> Project: FOP
> Issue Type: Bug
> Components: font/opentype
> Affects Versions: 2.7
> Reporter: Stephan Wienczny
> Priority: Critical
> Attachments: conf.xml
>
>
> When running FontInfoFinder::find on NotoSansCJK-Regular.ttc or
> NotoSerifCJK-Regular.ttc this causes an NPE in line 219
> {code:java}
> for (String fontName : ttcNames) { {code}
> because ttcNames is null.
> TTFFile::getTTCnames may return null for invalid files. This case should be
> handled in FontInfoFinder.
