JPA insert issue - OneToMany/ManyToOne with EmbeddedId - spring

Question

I've an issue where parent is generating multiple insert statements thereby having challenge with saving child. Code:
#Entity
#Table(name="PARENT")
public class Parent implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
private ParentPK id;
#Column(name = "FIRST_NAME")
private String firstName;
#Column(name = "LAST_NAME")
private String lastName;
// bi-directional many-to-one association to ParDepend
#OneToMany(fetch=FetchType.EAGER, mappedBy="parent", cascade={CascadeType.ALL}, orphanRemoval=true)
private List<ParDepend> parDepends;
//getters, setters, add (for parDepends), remove (for parDepends)
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Borrower other = (Borrower) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
return true;
}
}
#Embeddable
public class ParentPK implements Serializable {
//default serial version id, required for serializable classes.
private static final long serialVersionUID = 1L;
#SequenceGenerator(name = "parSeq", sequenceName = "PARENT_SEQ", allocationSize = 1, initialValue = 1)
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "parSeq")
#Column(name="PAR_SK_SEQ")
private long parSkSeq;
#Column(name="PAR_REV_NUM")
private long parRevNum;
//getter, setters
//JPA generated equals and hashcode
}
#Entity
#Table(name="PAR_DEPEND")
public class ParDepend implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
private ParDependPK id;
private BigDecimal age;
//bi-directional many-to-one association to Parent
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumns({
#JoinColumn(name="PAR_REV_NUM", referencedColumnName="PAR_REV_NUM"),
#JoinColumn(name="PAR_SK_SEQ", referencedColumnName="PAR_SK_SEQ")
})
private Parent parent;
//getters, setters
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
BorrDepend other = (BorrDepend) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
return true;
}
}
#Embeddable
public class ParDependPK implements Serializable {
//default serial version id, required for serializable classes.
private static final long serialVersionUID = 1L;
#Column(name="PAR_SK_SEQ", insertable=false, updatable=false, nullable=false)
private long parSkSeq;
#Column(name="PAR_REV_NUM", insertable=false, updatable=false, nullable=false)
private long parRevNum;
#SequenceGenerator(name = "parDependSeq", sequenceName = "PAR_DEPEND_SEQ", allocationSize = 1, initialValue = 1)
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "parDependSeq")
#Column(name="SEQ_NUM")
private long seqNum;
#Column(name="REV_NUM")
private long revNum;
//getter setter
//JPA generated equals and hashcode
}
I'm using dozer to convert UI returned data to JPA entity mapping. Then using Spring Repository to save and flush Borrower entity. It is generating borrower sequence twice and inserting nulls for borrower, instead of actual value. My assumption is that actual values are in memory to be inserted with first sequence, while second sequence will null data is getting inserted. Any suggestions on issue with JPA mappings? I do not see dozer an issue as logs shows JPA entity is property created as
{parent=Parent [id=ParentPK [parSkSeq=0, parRevNum=0], firstName=ABCD, lastName=XYZ, parDepends=[ParDepend [id=ParDependPK [parSkSeq=0, parRevNum=0, seqNum=0, revNum=0], age=31]]]}
JPA Ecliselink version 2.5.0-RC1
Spring Data JPA framework version 1.7.1.RELEASE
Please, let me know of any other information required for this question.
Edit: update dozer logs.
