Spring data JPA: cannot persist object with attribute of type Point

[Spring data JPA: cannot persist object with attribute of type Point]

While trying to persist an object with an attribute of type Point, defined as follows:

 

@Entity
@Table(name = "event")
public class Event {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private long id;

    @Column(columnDefinition = "POINT")
    private Point coordinate;

}

I'm getting the error Data truncation: Cannot get geometry object from data you send to the GEOMETRY field.

The corresponding database table is defined as follows:

 

create table event
(
   id bigint not null auto_increment,
   coordinate POINT,
   primary key (id)
)
engine= InnoDB;

What am I missing?
