Can't test with Ejb3Unit

I downloaded the sample project from Ejb3Unit, imported it into eclipse and run it as JUnit Test -> no errors.

BUT when I try to test my own entity class I always get an OutOfMemoryError!

@Entity
@Table(name = "AUTOR")
public class Author implements Serializable {

private int id; 
private String name;    
private Date created;

@Id
@GeneratedValue
public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@Column(name = "creation_timestamp", nullable = false)
public Date getCreated() {
    return created;
}

public void setCreated(Date created) {
    this.created = created;
}   
}


public class AuthorTest extends BaseEntityFixture<Author> { 

public AuthorTest() {
    super(Author.class);
}   
}

do I have to do some changes in any properties file or is the problem anywhere else?

Increasing eclipse's -Xmx configuration value (e.g. in eclipse.ini) should help.

For more information, see:

http://wiki.eclipse.org/FAQ_How_do_I_increase_the_heap_size_available_to_Eclipse%3F

The issue could be related to size of random strings ejb3unit uses to automatically test your entity bean, try changing @Column(length = ...).

The default value for length is 255, which isn't a whole lot.
