Ewen Cheslack-Postava commented on KAFKA-5067:
----------------------------------------------
This also looks like it has more to do with the [the JDBC
connector|https://github.com/confluentinc/kafka-connect-jdbc] than with the
Kafka Connect framework. It's likely that any bug here should be filed for the
connector rather than the framework.
