------------------------------------
Summary: Remove fallbacks for service users resolution
Key: SLING-4461
URL: https://issues.apache.org/jira/browse/SLING-4461
Project: Sling
Issue Type: Improvement
Components: Service User Mapper
Reporter: Marius Petria
ServiceUserMapperImpl has several levels of fallback for
service user resolution (fallback to bundle default, or to global
default). While this offers a lot of flexibility, it introduces non-determinism
in a security feature. If defaults are set, it can
happen (especially at startup) that code is executed using different
serviceUsers, e.g. a component can execute using the bundle default or
global default until its specific subService is available, and it can be
easily imagined how this can cause subtle errors.
