> 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}}.
