Cassandra 3 - Guava error on insert (not on update)

Hi all, Out of the blue, I started receiving a strange error message when inserting a new row that seems related to guava (see below). I really don't understand what is going on. I didn't change anything on the server and everything works fine if the query is an update (the row already exists)
