Description

If an anonymous inner class is defined inside of a static method, "this" does not reference what it should:

Demo.groovy

class Demo {
    static void main(arg) {
        def r = new Runnable() {
            void run() {
                if(this instanceof Runnable) {
                    println 'Yep'
                } else {
                    println 'Nope'
                }
            }
        }
        r.run()
    }
}

$ groovy Demo
Nope

2.3.3 is the only version I have tested this with.
