[jira] [Commented] (GROOVY-8243) SAM trait coercion via middle interface

["Josh DeWitt (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-8243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17574402#comment-17574402 ] 

Josh DeWitt commented on GROOVY-8243:
-------------------------------------

Not sure if this is the appropriate ticket, but as of 3.0.11 the below code no longer works; it now prints out {{null}} instead of {{{}string b{}}}. Seems like it is relying on the native object instead of the {{{}$closure$delegate$map{}}}?

{code:java}
abstract class A {
    String b
}

def a = [getB: { 'string b' }] as A
println a.b
{code}

>     def bar(double j) {
>         println "bar $j"
>     }
> }
> interface F extends T {}
> F t = { println "closure $it" }
> t.foo(42) // `closure 42`
> t.bar(43) // `closure 43.0`; should be `bar 43.0`

> Changing variable type to {{T}} works as expected.
