[jira] [Created] (GROOVY-9276) Improve the performance of parsing

Daniel Sun created GROOVY-9276:
----------------------------------

             Summary: Improve the performance of parsing
                 Key: GROOVY-9276
                 URL: https://issues.apache.org/jira/browse/GROOVY-9276
             Project: Groovy
          Issue Type: Improvement
          Components: parser-antlr4
            Reporter: Daniel Sun
            Assignee: Daniel Sun
             Fix For: 3.0.0-rc-1


When semantic predicate fails, {{FailedPredicateException}} will be thrown to change the control flow. But as we all know, filling the stack trace is expensive especially when FailedPredicateException is thrown frequently. So eliminating the stack trace can improve the performance of parsing to some extent.
