import java.sql.DriverManager;
 
 
 
public class p2 {
 
public static void main(String[] args) throws Exception {
 
   Connection conn = DriverManager.getConnection("jdbc:mariadb://moe:10309/test", "user", "pwd");
 
   DatabaseMetaData metadata = conn.getMetaData();
 
   System.out.println("Driver Name = " + metadata.getDriverName());
 
   }
 
}

Changed for next version. Check that hibernate doesn't rely on name for automatic Dialect resolver, and it rely on first part only (that getDriverName start with "MariaDB"

Many other libraries and products do not yet know Database Type = MariaDB (from metadata point of view) and fail to work with driver 2.4.0 because of change made in org.mariadb.jdbc.MariaDbDatabaseMetaData#getDatabaseProductName (Spring Batch, JQM, etc.)
This means that for many projects update of MariaDB driver means an upgrade of other libraries. That can be too hard to complete.

Is it possible to get some flag to preserve compatibility with other 3rd party libraries? Probably, minor release with such a feature would be helpful.

Hi mtykhenko, an option in 2.4.1 named "useMysqlMetadata" permit to force databaseMetaData.getDatabaseProductName() to return "MySQL" (default now return "MariaDB" or "MySQL" according to server type) . This option permits compatibility with frameworks that doesn't support "MariaDB" type.
