When I use JsonExtractor and JsonAssertion test looks success via maven build also if there is nullpointer. Nullpointer appears when the server which I test does not response json, so if result is empty.
I also configure test to first check response code and if response code is not 200 it should stop thread but the results are the same.

Do you have JSON plugin installed/available at all?
CannotResolveClassException is quite informative
