Re: [eclipselink-users] EntityManager.find returning instance of wrong type 
Yes, a workaround would be

  Base b = em.find(Base.class, id);

  if (b instanceof Foo) {
     doStuffToFoo((Foo) b);
  else if (b instanceof Bar) {
     doStuffToBar((Bar) b);
  } 

However, I think it is odd behavior that an object of the wrong type is
returned. Can anyone tell me if this really is "by design"?
