I've encountered several issues with JSON serialization yesterday: - int and long are decoded as Integer when using JSONObject.get(key) method => ClassCastException when the code is expecting a long and receives a integer - String[] parameters are deserialized as Object[] => All the createConnectionFactory() methods don't work: the ManagementService will not find the matching method since Object[] and String[] are different types (and not assignable). I've hacked 1 createConnectionFactory method to pass the parameters as Object[] to run the JORAM tests but all the others methods won't work.
