为什么MetaModel参数为null

Question

I have a very simple model class.

@Entity
@Table(name="reach")
public class Reach {

    @Id
    @Column(name = "uid")
    private Long uId;

    @Column(name = "reach_30")
    private Integer reach30;

... getters, setters..
}

And here is my meta model

@StaticMetamodel(Reach.class)
public class Reach_ {
    public static volatile SingularAttribute<Reach, Long> uId;
    public static volatile SingularAttribute<Reach, Integer> reach30;
}

And when i print following

    System.out.println("==============="+(Reach_.uId));
    System.out.println("==============="+(Reach_.reach30));

I get object value for uId BUT NULL for reach30 . Any idea whats going on here.

Thankx

Problem was with eclipse. Needed to clean and restart computer to get it working. But not a problem with code
