Jeroen van der Grift commented on FOP-2704:
-------------------------------------------
I'm facing the same exception when I try to use Google Noto font
(NotoSans-Light.ttf).
Adding <complex-scripts disabled="true" /> doesn't seem to work.

> There are two changes that should be done to the
> {{OTFAdvancedTypographicTableReader}}.
> # The method {{readGDEFMarkGlyphsTableFormat1}} should catch this exception
> # The method {{constructLookupsLanguage}} should check if the {{languages}}
> parameter is null.
> After these changes, the PDF is produced and it looks good. I am not sure
> what are the side effects on the font that is embedded into the PDF..
