@CompileStatic
interface IService<T> {
    default void save(T entity) {
        System.out.println(entity);
    }
}

@CompileStatic
interface IServiceString {
    default void save(String entity) {
        System.out.println(entity);
    }
}

@CompileStatic
class TestGenericGroovy implements IService<String> {
    void save(String entity) {
        // IService<String>.super.save(entity) // works
        super.save(entity) // doesn't work: Groovyc: [Static type checking] - Abstract method save(T) cannot be called directly
    }
    static void main(String[] args) {
        new TestGenericGroovy().save("test")
    }
}
