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

[Luca Rondanini]

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)

Did you see this problem before? Where would you look for possible
solutions?

Thanks a lot!
Luca
