I will report back with the results.
I set rewriteBatchedStatements=false and it no longer raises ClassCastException.

I am not clear.
What is going on inside the driver when performing updates with multithreading and rewriteBatchedStatements=true?
I have no way of knowing if the behavior with this parameter is due to the spec or a bug.
