Entity with multiple embeddable records is broken in EclipseLink

[njr-11]

After fixes were applied for #29117 , tests fail when trying to insert an entity that has multiple embeddable records. The database raises an error,

Column name 'X' appears more than once times in the column list of an INSERT statement

After EclipseLink tries to use the same column for both embeddable field.

Entity:

@Entity
public class Segment {

    @GeneratedValue
    @Id
    public Long id;

    @Embedded
    @Column(nullable = false)
    public Point pointA;

    @Embedded
    @Column(nullable = false)
    public Point pointB;
}

Embeddable class:

@Embeddable
public record Point(int x, int y) {
}

SQL that we see EclipseLink using:

CREATE TABLE WLPSegment (ID BIGINT NOT NULL, X INTEGER, Y INTEGER, PRIMARY KEY (ID))

INSERT INTO WLPSegment (ID, X, Y, X, Y) VALUES (?, ?, ?, ?, ?)
