Description
The schema that was being used when this error was produced is attached.
Whenever I write a null value to any of the id, name, or description fields for a LOAD_BALANCER_POOL udt in the pools set of the LOAD_BALANCER_SERVICE table or to the name, enabled, description, or ip_addresses fields of the LOAD_BALANCER_VIRTUAL_SERVER table in the virtual_servers set of the LOAD_BALANCER_SERVICE table, I get the following error from cqlsh:
<ErrorMessage code=0000 [Server error] message="java.nio.BufferUnderflowException">
When doing the same from the Java Datastax driver, this seems to succeed on the first write but fail with a timeout exception on all subsequent writes until either the table is truncated or both the pools and virtual_servers collections are both written as empty sets.
Having null values in other UDT fields in the hierarchy doesn't seem to cause any issues.
When I restart Cassandra after having these errors, Cassandra fails to start and throws the following error when trying to replay the commit logs:

I'm not sure if null values are supposed to be acceptable for UDT fields, but in any case, it would be nice to handle these errors more gracefully.
