java中这种结构可以正常运行，会引发一些问题吗？？？

public class SuperClass {
    public String test() {
        System.out.println("===SuperClass test " );
        return "new Exception()";
    }
}
...
public class SubClass extends SuperClass {
    public SubClass() {
    }

    public Exception test() {
        System.out.println("===subclass 我的返回值是Exception");
        return new Exception();
    }
}

...
Exception test1 = new SubClass().test();
String test2 = new SuperClass().test();
