Problem conclusion
The warning message indicates a code path which should be, but has not yet been enabled for annotation caching. The presence of the warning message indicates that redundant annotation scanning steps are being performed. The result is a reduction of the performance improvements which are provided by annotation scanning. Application function is not impacted: The problem is entirely a performance performance and the presence of the warning to server logs. The problem was fixed by a code update which properly enables the problem code paths to use annotation caching. The fix for this APAR is currently targeted for inclusion in fix pack 20.0.0.2.
