[jira] [Commented] (GROOVY-7797) Private trait method called from within a closure has the wrong "this" context

Aaron Long commented on GROOVY-7797:
------------------------------------

This issue does not affect Groovy 2.4.1. It seems to have been introduced with the other breaking trait changes in 2.4.2

>          Issue Type: Bug

> Calling a private trait method from within a closure results in a MethodMissing exception. It looks like within the closure, `this` is referring to the implementing Class and not the instance.
> This might be related to GROOVY-7373. The problem is that calling getDelegate() doesn't work as delegate also seems to have the wrong context.
> {code}
> trait MyTrait {
>     void greeter() {
>         {-> doGreeting("hi")}.call()
>     }
>     private void doGreeting(String message) { println message }  
> }
> class MyClass implements MyTrait { }
> new MyClass().greeter()
> {code}
> If you make the doGreeting method above `static`, it will work properly.
