Sylvain Lebresne resolved CASSANDRA-10891.
------------------------------------------
Resolution: Invalid
As indicated by the stacktrace, this is a driver exception and you may open a
ticket on java driver JIRA if you wish to:
https://datastax-oss.atlassian.net/browse/JAVA.
I will note however that {{null}} values are not supported by CQL so you simply
cannot do what you are trying to do: you need to make sure you have no nulls.
Whether the driver should throw a more meaningful exception in that case is
something I'll left to the drivers maintainer to answer.
> Cassandra driver doesn't allow to insert null as a value in map
