Como sugiere el título, recibo un error al ejecutar las pruebas de Play 2.0.1 utilizando una aplicación falsa con H2 en la memoria.

Configuré una prueba unitaria básica:

public class ModelTest {
    @Test
    public void checkThatIndustriesExist() {
        running(fakeApplication(inMemoryDatabase()), new Runnable() {
            public void run() {
                Industry industry = new Industry();
                industry.name = "Some name";
                industry.shortname = "some-name";
                industry.save();
                assertThat(Industry.find.all()).hasSize(1);
            }
        });
    }

Que produce la siguiente excepción:

Mi modelo se ve así:

@Entity
@Table(name = "industry")
public class Industry extends Model {
    @Id public Long id;
    public String name;
    public String shortname;

    // called in the view to trigger lazy-loading
    public String getName() {
        return name;
    }

    public static Finder<Long, Industry> find = new Finder<Long, Industry>(Long.class, Industry.class);
}

... y finalmente la parte relevante de mi evolución inicial:

create table industry (
    id        bigint not null,
    name      varchar(255),
    shortname varchar(255),
    constraint pk_industry primary key (id)
}

create sequence industry_seq start with 1000;

Todo funciona bien ejecutándose en mi base de datos PostgreSQL, y desde mi punto de vista, el código no es diferente delPlay2.0 Computer Database Sample.

Estoy feliz por cualquier ayuda - gracias!
