Hi List FWIW, I took the liberty of vandalising the Antlr4 'parrot' parser from its Java 8 style into Java 7.
The result is found in: https://github.com/apache/groovy/pull/485 Travis tested using JDK8 and passed, my own build on Java 7 (On OS X) passes too. This would make the parser ready for adoption in Groovy 2.5. Kind regards Jesper
