> This is a different behavior to former AS versions and a huge performance issue.
> From the EJB spec the entities must be flushed due to have the correct result of the invoked finder.
> ejbFindByPrimaryKey() is special as there is no need to flush other instances.
> It is ensured that the entity is found nevertheless whether it is changed or not as the 'cache' is evaluated first.
