Generics for ExternalContext#getInitParameterMap()

In JSF 2.2 the ExternalContext#getInitParameterMap() returns a raw Map. Starting with JSF 2.3, this method was extended to support generics types.

JSF 2.2 - RAW MAP

Map initParamMap = FacesContext.getCurrentInstance().getExternalContext().getInitParameterMap();

JSF 2.3 - Map<String, String>

Map<String, String> initParamMap = FacesContext.getCurrentInstance().getExternalContext().getInitParameterMap();
