Description
NamespaceMapper
Deprecated.
Per session namespace mapping is not supported anymore.

The `SlingRepository` extends the standard JCR repository interface with two methods: `SlingRepository.getDefaultWorkspace()` and `SlingRepository.loginAdministrative(String)`.
SlingRepositoryInitializer
All active `SlingRepositoryInitializer` services are called before making the `SlingRepository` service available, and can perform initializations on it, like creating service users, setting up initial access control, migrating content in upgrades, etc.
TooManySessionsException
Deprecated.
Session pooling has been removed and thus this exception is not used any more.
