[jira] [Comment Edited] (LUCENE-6417) Upgrade ANTLR to version 4.5

    [ https://issues.apache.org/jira/browse/LUCENE-6417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14652029#comment-14652029 ]

Sorry, Mike and Uwe, for the delayed response.  I was actually on vacation the previous week.  I'll fix the pre-commit and make the suggested changes.  The ASM did not change at all (other than by mistake :) ), I was just forced to re-organize the ASM generation code into smaller chunks for the Antlr 4.5 visitor.  Thanks for reviewing the patch!

> I would like to upgrade ANTLR from 3.5 to 4.5.  This version adds several features that will improve the existing grammars.  The main improvement would be the allowance of left-hand recursion in grammar rules which will reduce the number of rules significantly for expressions.
> This change will require some code refactoring to the existing expressions work.
