I based the TriG parser on Jena's N3 parser, which was implemented  
using AntLR.

Jena has since removed that parser and replaced it with a Turtle  
parser, which uses JavaCC.

I think you have two options:

a) pull the AntLR bits from the old Jena repository and put them into  
NG4J

b) create a new TriG parser based on Jena's new Turtle parser.

For someone who is already familiar with JavaCC, option b) is likely  
not too much work, and would produce a cleaner and more maintainable  
result. But a) would be quicker and maybe Good Enough.

Best,
Richard
