ASF GitHub Bot commented on GROOVY-12707:
-----------------------------------------
paulk-asert opened a new pull request, #3237:
URL: https://github.com/apache/groovy/pull/3237
The named-group check scanned the regex text for (?<name> openers, which
missed names spelled with COMMENTS-mode whitespace or comments and counted
openers in quoted text or character classes. Decide by compiling the regex with
a named backreference appended, which the JDK rejects exactly when the group is
undefined; a name that is not a legal group name is rejected first. The scan
now only lists names for the message, each confirmed the same way.
Matcher.start and Matcher.end are checked like group.
