Can embeddable class have constructors?

I have a class with embeddable annotation and, when I try to pass an instance to an entity, I get an exception:

org.hibernate.InstantiationException: No default constructor for entity: : entity.D3

enum Figure {
    SQUARE, TRIANGLE
};

@Embeddable
public class D3 {
    float z;
    @Enumerated(EnumType.STRING)
    Figure figure;

    public D3(float z, Figure f) {
        this.z = z;
        this.figure = f;
    }
}

It's looking for a default constructor (i.e. parameterless), in addition to any you have defined:

@Embeddable
public class D3 {
    float z;
    @Enumerated(EnumType.STRING)
    Figure figure;

    public D3() { //I've added this
    }

    public D3(float z, Figure f) {
        this.z = z;
        this.figure = f;
    }
}
