The exact time point when auto-assigned identity value of a persistent entity
is assigned is rather ill-defined in JPA spec. OpenJPA will assign this
identifier when the new entity is flushed/committed or when explicitly
requested via SPI-specific API.
For example, both of the following assertions should pass for entity with an
auto-assigned identifier
em.persist(pc);
em.flush();
assertNotNull(pc.getId());
or
em.persist(pc);
assertNotNull(OpenJPAPersistence.cast(em).getObjectId(pc));
ill-defined
