Ok, had the same issue. Adding prefixes fixed the problem for me:

from:

`
@Entity
@Table(name = "result_man")
@Proxy(lazy = false)
public class ResultManEntity {
@Id
@GeneratedValue
@Column(name = "id", unique = true, length = 128)
private long id;
private String key;
private int score;
private int index;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "result_id")
private ResultEntity result;
}`

to:

`@Entity
@Table(name = "result_man")
@Proxy(lazy = false)
public class ResultManEntity {
@Id
@GeneratedValue
@Column(name = "id", unique = true, length = 128)
private long id;
private String _key;
private int _score;
private int _index;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "result_id")
private ResultEntity result;`
