> Rehydrating a @CompileStatic packed closure ignores the new this object and
> keeps calling the original owner
> ------------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-12666
> URL: https://issues.apache.org/jira/browse/GROOVY-12666
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> {code:groovy}
> import groovy.transform.CompileStatic
> import groovy.transform.PackedClosures
> class D {}
> @CompileStatic
> @PackedClosures
> class O {
> String name
> String foo() { 'foo ' + name }
> List run(O b) {
> Closure c1 = { -> foo() }
> Closure c2 = { -> name }
> [c1.rehydrate(null, b, b)(), c2.rehydrate(null, b, b)(),
> c1.rehydrate(new D(), new D(), new D())()]
> }
> }
> println new O(name: 'a').run(new O(name: 'b'))
> {code}
> *Actual:* {{[foo a, a, foo a]}}. The same happens without the annotation when
> compiling with {{-Dgroovy.target.closure.pack=true}}.
> *Expected*, as with the closure class compiled without packing: {{[foo b,
> b]}}, then a ClassCastException from the third call, because D is not an O.
> A @CompileStatic closure class runs its body against getThisObject(). A
> packed closure dispatches its hoisted method to the receiver captured at
> construction, and Closure.rehydrate only replaces the visible owner, delegate
> and this object, so the new this object is silently ignored.
> Verified on 6.0.0 and master.
