java8新特性构造器引用问题

public class Employee {
    int id;
    String name;
    int age;
    double salary;

    public Employee() {
    }

    public Employee(int id) {
        this.id = id;
    }

    public Employee(int id, String name, int age, double salary) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.salary = salary;
    }
}

@Test
    public void test1(){
        Supplier<Employee> sup1 = () -> new Employee();
        System.out.println(sup1.get());

        System.out.println("****************************");

        Supplier<Employee> sup2 = Employee::new;
        System.out.println(sup2.get());
    }

调试结果是：
com.nuist.java2.Employee@649d209a
****************************
com.nuist.java2.Employee@357246de

为什么不是：
Employee{id=0,name='null',age=0,salary=0.0}
请问是哪里出问题了？急急急
