It's a guess - shot in the dark, but worth to try out - why do you
assign -1 to the entity primary key? 0 is the default value so
everything that's different than the default value is likely
considered as a valid persistent identifier.
You may eventually want to run the sample with em.persist(em.merge(group)).
