Oracle TopLink - Version 11.1.1.6.0 to 12.1.2.0.0 [Release Oracle11g to 12c]Information in this document applies to any platform.
Symptoms
One to one relationships marked as lazy are being triggered unnecessarily when the objects are queried via a stored procedure in a transaction and REFRESH hint (RefreshIdentityMapResult) is set to true.
As a result, additional queries are issued to the database when they are not needed which lead to performance degradation.

No - Toplink 11.1.1.4/ Eclipselink 2.1.2
