Whilst (pulling my hair out) writing the cassandra test suite, after many failing tests and some debugging I noticed that, under many InvocationTargetException's, CassandraMapping#loadConfiguration() throws the following
Caused by: java.lang.NullPointerException

when it cannot load the correct configuration from gora.properties. I know it is not great practice to put the while method in a try catch block so would be good to work towards a better solution.
