C3P0 Driver Issue

[mohitdilwaria]

Our application uses multitenancy, where the first tenant employs MariaDB, and the second tenant is configured to use MySQL 8. However, we have encountered a challenge where, for the second tenant using MySQL 8, the connection attempts seem to be made with the MariaDB JDBC driver instead. Despite providing the correct JDBC URL, username, and password for MySQL8, I'm receiving an error indicating that the connection is being attempted with the MariaDB JDBC driver. This has led to an "Access denied for user" exception

Below are the logs As you can see we have jdbcurl as mysql
