In 11.2, use of the SQL Query Result Cache is enabled on a query, either directly through the /*+ RESULT_CACHE */ hint, or indirectly through table annotations or by using the result_cache_mode=FORCE parameter setting. This query calls one or more PL/SQL functions. Unexpected (wrong) results are seen from the query on an intermittent basis.
This may occur after an upgrade from 11.1 to 11.2.
