Tedy,
A particular bean instance is associated with a particular
primary key from an ejbActivate/ejbCreate to an ejbPassivate/
ejbRemove. As such, the first sequence below is not valid.
The second and third sequences appear to be correct. Note
that in all sequences, the ejbLoad after ejbCreate is atypical,
although strictly speaking not incorrect.
As such, caching based on the primary key is allowed between
the various boundary calls.
