---------------------------------------
Summary: Regression performance issue in string methods
Key: GROOVY-7873
URL: https://issues.apache.org/jira/browse/GROOVY-7873
Project: Groovy
Issue Type: Bug
Affects Versions: 2.4.7
Reporter: Tadas Krivickas
Priority: Critical
Starting with 2.4.7, performance in string processing (in certain scenarios)
has decreased dramatically. In our app it was from tens ms to 1+ minute. I
suspect the latest refactoring in string methods.
Attaching a test case.
