[jira] [Closed] (GROOVY-2641) Dynamically created closure handles delegate differently from statically created closure
[ https://issues.apache.org/jira/browse/GROOVY-2641?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul King closed GROOVY-2641.
-----------------------------
> Dynamically created closure handles delegate differently from statically created closure
> ----------------------------------------------------------------------------------------
>
> Key: GROOVY-2641
> URL: https://issues.apache.org/jira/browse/GROOVY-2641
> Project: Groovy
> Issue Type: Sub-task
> Components: groovy-runtime
> Affects Versions: 1.5.4
> Environment: CentOS 5 n Intel with java 1.6.0_03-b05
> Reporter: Bruce Cota
> Priority: Major
>
> The following script executes two closures. One is statically defined in class Test,
> the other is returned by Test.makeClosure(). In each case the delegate of the
> Closure is set to be an instance of class Delegate, but in one case a call to
> method "foo()" appears to resolve to Test.foo(), while in the second it appears
> to resolve to Delegate.foo().
> I showed this to Dierk at the G2 conference in Reston, and he asked me to post
> it as a bug.

> class Test {

> Closure dynamicClosure = new Test().makeClosure()
> dynamicClosure.setDelegate(new Delegate())

> Expected Output:
