> - There is a [bug](https://bugs.mysql.com/bug.php?id=106252) in the Connector/J 8.0 versions before 8.0.32, which might cause threads to hang when using TiDB versions earlier than v6.3.0. To avoid this issue, it is recommended that you use either MySQL Connector/J 8.0.32 or a later version, or the TiDB JDBC (see the *TiDB-JDBC* tab).
> - When you are using MySQL Connector/J 8.0 with TiDB v7.5.0, it is recommended to set the TiDB configuration item [`server-version`](https://docs.pingcap.com/tidb/v7.5/tidb-configuration-file#server-version) to `"5.7.25-TiDB-v7.5.0"`. MySQL Connector/J attempts to access the `information_schema.KEYWORDS` table if the TiDB server reports a version of MySQL 8.0.11 or later. However, this table is not present in TiDB v7.5.0.
