Hibernate with @CollectionTable removes the objects of set with same boolean value on update

I have the following structure:

public class Profile {
 ...

 @ElementCollection(targetClass = ProfileFieldImpl.class, fetch = FetchType.EAGER)
 @CollectionTable(name = "profileField", joinColumns = @JoinColumn(name = "profileId"))
 @OrderColumn(name = "fieldName")
 private Set<ProfileField> fields;

}

@Embeddable
public class ProfileFieldImpl {

    @AttributeOverride(name = "id", column = @Column(name = "rofileFieldId", nullable = false))
    private Long profileFieldId;

    private String name;

}

Now i'm adding a new column: publicField Added also the equals and hashCode mothods.

public class ProfileFieldImpl {

    @AttributeOverride(name = "id", column = @Column(name = "rofileFieldId", nullable = false))
    private Long profileFieldId;

    private String name;

    private boolean publicField;

    @Override
    public final boolean equals(final Object o) {
        if (o == this) {
            return true;
        } else if (o == null || !(o instanceof ProfileFieldImpl)) {
            return false;
        } else {
            final ProfileFieldImpl other = (ProfileFieldImpl) o;
            return EqualsUtil.equalsNullable(getName(), other.getName()) && EqualsUtil.equalsNullable(isPublicField(), other.isPublicField()));
        }
    }

    @Override
    public final int hashCode() {
        return HashCodeUtil.seed(HashCodeUtil.SEED_13).with(name).with(publicField).hashCode();
    }
}

Adding the following fields (Database fields):

1. name = "Field1", publicField = '0'
2. name = "Field2", publicField = '0'
3. name = "Field3", publicField = '1'
4. name = "Field4", publicField = '1'

How I do the update:

....
final ProfileImpl profile = getEntityManager().find(Profile.java, profileId, LockModeType.NONE);
final Set<ProfileField> fields = profile.getFields();

fields.stream().filter(field -> field.getName().equals(currentFieldName)).forEach(field -> {
    field.setName(updatedProfileField.getName());
    field.setPublicField(updatedProfileField.isPublicField());
});

getEntityManager().merge(profile);

The Issue:

When I'm trying to update the field3, the field4 is deleted; When I'm trying to update the field1, the field2 is deleted.

Do someone have any suggestion?

Finally I've found the issue and also the solution.

Because of using boolean as primitive instead of object was that issue.

Solution was to use the Boolean wrapper instead of the primitive.

private Boolean publicField;

Now is working properly without removing any other object.
