False positive in squid:S1604 (Anonymous inner classes containing only one method should become lambdas)

[mabbas]

Hello,

I think the Rule squid:S1604 should not raise an issue for the following example:

public class S1604Test {

    public static void main(String[] args) {

        new S1604() { // An Issue squid:S1604 is raised by Sonar here:
                      // Make this anonymous inner class a lambda            
            @Override
            public void m1(String s) {
                // do Nothing
            }

        };

    }

    public interface S1604 {

        default void m1(String s) {}

        default void m2(String s) {}

        default void m3(String s) {}

    }

}

As you can see, the interface contains only default methods so a lambda can't be used.

I am using the version 5.1.1 of SonarJava and the version 7.0 of SonarQube
