NPE when doing a find()

Type: BugVersion: 1.4.0Priority: NormalStatus: FixedReplies: 1
#1

I added a simple User entity during Tomcat startup:

class User {

 @Id @GeneratedValue
private long id;

@Basic(optional = false)
private String firstName;
private String middleName;
@Basic(optional = false)
private String lastName;

}

Everything works fine until I restart the server, which does a em.find(User.class, 1).  Then this happens:

This used to work in previous ObjectDB version.

It seems that this is a bug that was added in build 2.2.1_02 and was fixed in build 2.2.1_03.

Please try the last build (2.2.1_03).
