When I read the ejb 1.1 entity state machine diagram p.102, the ejbOjbect does
not get associated with the bean for ejbFind (as I understand it).
For ejbFind the enity bean stays in the pooled state, it only moves to the ready
state (and is associated with an ejbObject) for ejbCreate, or ejbActivate.
