When trying to load any font in OTF format the following exception is thrown:

Look at the very last offset read here: https://github.com/sgothel/jogl/blob/master/src/jogl/classes/jogamp/graph/font/typecast/ot/table/CffTable.java#L200

Yes, even though I have updated our Typecast branch - it is not supported.

There exist an experimental branch https://github.com/haumacher/typecast/commits/documentation
addressing some of these issues, but not yet fully functional.

Hence I put this as WONTFIX for now as TTF is OK for now.
We may revisit this if interest (and contracts) come up.
