*<B>Assertion Description: </B>
The refreshAll() updates the values in the parameter
instance[s] from the data in the data store. ((The intended use is for optimistic transactions where the state of
the JDO Instance is not guaranteed to reflect the state in the data store. This method can be used to minimize
the occurrence of commit failures due to mismatch between the state of cached instances and the state of
data in the data store.)) This can be tested by using 2 PersistenceManagers, independently change an object,
then refresh.
