Folks, Version 4.6 of ANTLR was released[1] on Dec 15, 2016 and includes tons of bug fixes and performance improvements. I have created DRILL-5348[2] to track this work.
I would like to hear any comments and/or concerns form the team before I test and put a patch. I expect to merge it after 1.10 is released. aditya... [1] https://github.com/antlr/antlr4/releases/tag/4.6 [2] https://issues.apache.org/jira/browse/DRILL-5348
