Jiabao Sun commented on FLINK-34259:
------------------------------------
[~martijnvisser]
It seems introduced by
[FLINK-34090](https://issues.apache.org/jira/browse/FLINK-34122)
It doesn't seem to break public interfaces, and I think we only need to make
some adjustments in the testing of the JDBC connector.
