[jira] [Resolved] (LUCENE-5839) Regex bug in AnalyzingQueryParser

["Michael Sokolov (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-5839?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Sokolov resolved LUCENE-5839.
-------------------------------------
    Resolution: Fixed

AnalyzingQueryParser no longer exists. I also grepped for `wildcardPattern` just to make sure this usage didn't persist in some other class and couldn't find it: I think it's safe to close this now

> Dennis Walter recently pointed out this bug on dev@lucene.apache.org:
> "  // gobble escaped chars or find a wildcard character 
>   private final Pattern wildcardPattern = Pattern.compile("(\\.)|([?*]+)");
> The first group will match a literal dot ("."), while its intention seems to be to match a backslash and a single character. So the expression should instead be "(\\\\.)|([?*]+)"  "
