Description

When a pure function with only terminal arguments (or with no arguments) is used in a where clause, it's executed at prepare time and Server.CURRENT_VERSION passed as the protocol version for serialization purposes. For native functions, this isn't a problem, but UDFs use classes in the bundled java-driver-core jar for (de)serialization of args and return values. When Server.CURRENT_VERSION is greater than the highest version supported by the bundled java driver the execution fails with the following exception:

This is currently the case on trunk following the bump of Server.CURRENT_VERSION to 4 by CASSANDRA-7660.
