 * <B>Assertion Description: </B> The refreshAll(Object[] pcs) 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.
