> This is a variation of GROOVY-6777, GROOVY-6809 and GROOVY-7609.  A constructor's parameter may not presently be defaulted  by a value expression using a non-static inner class (including anon. inner).  This is likely caused by the uninitialized "this" reference that is supplied to the constructor of the non-static inner class.
> {code:groovy}
> // Error: Apparent variable 'this' was found in a static scope but doesn't refer to a local variable, static field or class.
> class Outer {
>   class Inner {} // make this static and all is well
>   Outer(Inner inner = new Inner()) {
>   }
> }
> new Outer()
> {code}
> {code:groovy}
> class C {
>   C(Runnable runner = new Runnable() { void run() {} }) {
>     //                ^^^^^^^^^^^^^^ enclosing method not set and ...
>     this.runner = runner
>   }
>   Runnable runner
> }
> new C().runner.run()
> {code}
