 * <B>Assertion ID:</B> A12.5.1-5B <br>
 * <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.
