Hi, i tryed updating the mysql connector in the gerrit project from 5.1 to 6.x. But it is failing because it is not applying the schema correctly now.

I think it is caused by https://github.com/mysql/mysql-connector-j/commit/3d3d0c157491d98b077429e0a5e23331dc69b0b0#diff-6a68eedf6a3f272bae764dc0ecc4eba8 but no evidence yet, ie haven't been able to revert it to try. But the traceback here

leads to executeBatch

But we use gwtorm, and it's an int but in the mysql connector it was changed to a long and made a private function.

https://github.com/GerritCodeReview/gwtorm/blob/master/src/main/java/com/google/gwtorm/schema/sql/SqlDialect.java#L434

In the mariadb connector, it is a int https://github.com/MariaDB/mariadb-connector-j/blob/e01335be8056d27f830038b6a276197d8113e102/src/main/java/org/mariadb/jdbc/MariaDbPreparedStatementServer.java#L218

See https://bugs.chromium.org/p/gerrit/issues/detail?id=7331 our issue.

wondering could we have help please to allow us to upgrade?
