Reading with navigation properties doesn't work

I've found new 2.0.10 issue.

If I send 
GET .../Example/ODataService.svc/SubEntitys(2)?$format=json
I receive existed DB relevant data with id=2.

But If I request the same data but using defined Navigation Property
GET .../Example/ODataService.svc/MainEntitys(1)/SubEntityDetails(2)?$format=json
I receive exception "Requested entity could not be found."

JPA entities and Navigation Properties are defined ok.
The same request with Olingo 2.0.9 version works ok and receive relevant DB data.

Please fix.

thx,

Janusz

My entities are:

 

@Entity
@Table(name="MainEntitys")
public class MainEntity

{ @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) private Integer id; @Column private String name; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "MainEntity") private List<SubEntity> subEntitys = new ArrayList<SubEntity>(); ... }

 

@Entity
@Table(name = "SubEntitys")
public class SubEntity

{ @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) private Integer id; @Column private String name; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "MainEntity_id", nullable = false) private MainEntity mainEntity; ... }
