[hibernate-dev] Antlr 4 PoC

[Steve Ebersole]

I started working on a proof-of-concept for using Antlr 4 for query parsing
in Hibernate.  It is very rudimentary at this point.  It is pushed to
GitHub here: https://github.com/sebersole/hibernate-antlr4-poc

This is mean as an attempt to determine whether/how Antlr 4 could/would
work for our needs.  Because Antlr 4 was such a big deviation from versions
2 and 3 we need to see how we can map many of the paradigms and patterns we
use in our existing parsers.
