Future for the JOni regex library

[Jim Laskey (Oracle)]

I'll let "Dr. RegExp" Hannes Wallnöfer respond in full when he gets back (holidays in Europe and JavaOne in India), but we are interested in co-operating and work towards pushing back an improved RegExp into the JDK.  Hannes has already implemented 98% of byte code generation in Nashorn.  Just down to to the last few corner cases.

Cheers,

- Jim
