Description
An error is occasionally reported when the insert statement is executed in stream mode.

java.sql.BatchUpdateException: Failed to register class.

Contributor guide
Research direction
Start by tracing the reported exception through `JdbcThinConnection`, especially `StreamState.readResponses` and the batch-send-on-close path. Reproduce the intermittent failure with streamed inserts and inspect the server-side class registration response; done means identifying and fixing the cause so streamed inserts close without `Failed to register class`.
