Well, I'd strongly suggest changing the text to something like "if the parameters cannot be retrieved" or "if the provider does not support parameter retrieval". I've seen the existing text used in other classes, however, those methods are not abstract and do throw `UnsupportedOperationException`. Now that the method is made abstract to force the override, the text should be adjusted as well...
