This should be avoided, because it's prone to maintenance and security problems.
It's easy to get rid of it: the class o.a.t.parser.geo.topic.gazetteer.GeoGazetteerClient uses com.google.common.reflect.TypeToken. Since the project uses gson anyway, it could just be replaced with com.google.gson.reflect.TypeToken.
