WithParams
1) set(...) has been called to set value for this parameter.
2) The parameter is a public final field of this WithParams instance. This includes fields inherited from its interfaces and super-classes.
The subclass which implements this interface could meet this requirement by returning a
member field of the given map type, after having initialized this member field using the
ParamUtils.initializeMapWithDefaultValues(Map, WithParams)
method.
