------------------------------------------
    Affects Version/s:     (was: 7.0.0-alpha-1)

> 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.
