OpenJPA is firing separate query for embedded class in the entity though annotted at @EagerFetchMode(FetchMode.JOIN)

I have a Embedded class in my entity which has some common similar columns for all the tables.

e.g

@Entity
@Table(name = "MY_TABLE")
public class MyTable implements Serializable {

//... some specific fields here

@Embedded
@EagerFetchMode(FetchMode.JOIN)
private CommonRowDetails commonRowDetails;

//...getters and setter below
}

And the class CommonRowDetails contains some audit columns as

@Embeddable
public class CommonRowDetails implements Serializable {

@Column(name = "ROW_ADD_STP", updatable = false)
private Date rowAddStp;

@Column(name = "ROW_ADD_USER_ID", updatable = false)
private String rowAddUserId;

@Column(name = "ROW_UPDATE_USER_ID")
private String rowUpdateUserId;

@Column(name = "ROW_UPDATE_STP")
private Date rowUpdateStp;

//...getters and setter below

}

All above columns are part of same table "MY_TABLE"
So when I select the entity MyTable, I can see a separate query is getting executed for selecting (ROW_ADD_STP, ROW_ADD_USER_ID, ...) which is definitely not required. I also added the annotation @EagerFetchMode(FetchMode.JOIN) on field CommonRowDetails to select those with join/in same query.
Please help me to know, how to avoid OpenJPA firing a separate query.
