One To Many relationship without join table in EclpseLink

The following classes:

@Data
@Entity
public class Num {
 @Id
 @GeneratedValue
 private Integer id;

 private Integer value;

}

@Data
@Entity
public class Suma {
 @Id
 @GeneratedValue
 private Integer  id;

 private String  value;

 @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
 @JoinColumn( name = "sum_id")
 private List<Num> nums;
}

Generate the following tables:

CREATE TABLE SUMA (
  ID INTEGER NOT NULL,
  VALUE VARCHAR(255)
 );

CREATE UNIQUE INDEX SQL111206140004130 ON SUMA (ID ASC);

ALTER TABLE SUMA ADD CONSTRAINT SQL111206140004130 PRIMARY KEY (ID);

CREATE TABLE NUM (
  ID INTEGER NOT NULL,
  VALUE INTEGER,
  SUM_ID INTEGER
 );

CREATE INDEX SQL111206140004360 ON NUM (SUM_ID ASC);

CREATE UNIQUE INDEX SQL111206140003900 ON NUM (ID ASC);

ALTER TABLE NUM ADD CONSTRAINT SQL111206140003900 PRIMARY KEY (ID);

ALTER TABLE NUM ADD CONSTRAINT FK_NUM_SUM_ID FOREIGN KEY (SUM_ID)
 REFERENCES SUMA (ID);

CREATE TABLE SEQUENCE (
  SEQ_NAME VARCHAR(50) NOT NULL,
  SEQ_COUNT DECIMAL(15 , 0)
 );

CREATE UNIQUE INDEX SQL111206140004490 ON SEQUENCE (SEQ_NAME ASC);

ALTER TABLE SEQUENCE ADD CONSTRAINT SQL111206140004490 PRIMARY KEY (SEQ_NAME);
