Managing the user state in a standalone application is relatively easy. EBERT runs as both a standalone application (RCP, ERCP) and as a multiple-user application (RAP). To support both environments, we have to be careful how we store user state.
EBERT defines an Equinox/OSGi Service of type IUserContextService.java along with two different implementations. Implementations of this type are responsible for one thing: answer, when asked, the user state (an instance of IUserContext) for the current user.
The notion of "current user" is pretty simple in the standalone case: there is only one user. The StandaloneUserContextService
