Major Description
As described in OAK-132 and OAK-141, both methods are implemented by delegating back to the respective Session methods and writing a warning to the log. This might introduce difficult to diagnose errors for those clients that rely on being able to only save/refresh parts of the transient space. A better solution might be to detect whether a save/refresh covers all transient changes and only then delegate back to the respective Session operation but throw an UnsupportedRepositoryException otherwise.
