The following issue was raised by an Adobe partner...We are facing an
strange problem post AEM upgrade to 6.3.We have OSGI service
configurations, that has a default value in the code (usual
implementation). The service config property values are of course
modified in the environment from OSGI console
(http://:4503/system/console/config). This was working in AEM 6.1.
After the upgrade to AEM 6.3, we have noticed sometime in some of the
environments, the modified values are not getting picked up ...
