             Summary: Changed behavior of delegates in 4.0.0
                 Key: GROOVY-9768
                 URL: https://issues.apache.org/jira/browse/GROOVY-9768
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.5.13
            Reporter: Grzegorz Kaczmarczyk
            Assignee: Eric Milles
             Fix For: 2.5.14, 3.0.6


I've noticed difference in how maps behave when used as delegates between 2.5.12 (and earlier versions) and 2.5.13. Consider this code snippet:
{code:java}
class MapAsDelegateProblem {

    static void main(String[] args) {
        new MapAsDelegateProblem().problematicCode()
    }

    def problematicCode() {
        def map = [:]
        callForAProblem(map) {
            assert "abc" == BAR
        }
    }

    def <U> void callForAProblem(U target, Closure<?> closure) {
        closure.setDelegate(target)
        closure.setResolveStrategy(Closure.DELEGATE_FIRST)
        closure.call(target)
    }

    private static final BAR = "abc"
} {code}
In 2.5.x (up to 2.5.12) this code works just fine. Static field {{BAR}} is accessed from closure in line 10. But this breaks in 2.5.13. This affects also tests written in Spock. Utility method {{spock.lang.Specification::with}} works in the same way as {{callForAProblem}}.
