[ BUILD # : 201211190002 ]
[ JDK VERSION : 1.7.9 ]

Test case:

public class A {
    public Runnable create() {
        return new Runnable() {
            public void run() {
            }
        };
    }
}

Moving the "create" method to class B yields

public class B {

    public Runnable create() {
        return new Runnable() {
            () {
                <init>();
            }

            public void run() {
            }
        };
    }
}
