For reference here is a java 8 grammar for antlr 4. https://github.com/antlr/grammars-v4/tree/master/java8/Java8.g4
One good thing that groovy has for its version 2 to version 3 transition is that all the java libraries would be available. This would be a key difference with the python 2 -> 3 migration.
