A “session singleton” is an RWT-specific singleton, which provides access to a unique instance with session scope. This means that in the context of one user session getInstance(Class) will always return the same object, but for different user sessions the returned instances will be different. To archive it’s “magic”, session singletons should call SessionSingletonBase#getInstance(), which takes care of the proper scoping of the singleton instances.
