/**
* The EntityStore (formerly "CacheController" or simply "Controller") may
* throw this Error when used improperly such as by calling
* EntityStore.put(object) with a parameter whose class is not registered with
* the Controller. The Controller expects to be used properly: get, put, etc.
* should be called with valid parameters.
*
* In the example above, rather than throw the underlying NullPointerException
* (the Map lookup for the controlled EntityGroup will be null), the
* Controller throws a ControllerError to provide details useful in debugging
* an application. However, applications should never rely on these errors
* during routine use; the problems identified by these errors should be
* discovered during development testing.
