    public B b
    public X() {
        b = new B() {
            public String getFoo() {a}
        }
    }
}

class A {}
class B {
    B(){getFoo()}
    def getFoo(){}
}

def x = new X()

Fixed in master and 1.8.x branch. However, I'm not closing it since backporting to 1.7.x is still under discussion.
