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.
