Description

When running FontInfoFinder::find on NotoSansCJK-Regular.ttc or NotoSerifCJK-Regular.ttc this causes an NPE in line 219

for (String fontName : ttcNames) { 

because ttcNames is null.

TTFFile::getTTCnames may return null for invalid files. This case should be handled in FontInfoFinder.
