    Description

      Using MySQLDataSource or MariaDbDataSource to connect from pool has a regression :

      MariaDbDataSource datasource = new MariaDbDataSource();
      datasource.setUser("USER");
      datasource.setPassword("PWD");
      datasource.setUrl("jdbc:mariadb://localhost:3306/db");

      Connection will use current current windows user (if using windows), not user "USER1"

      MariaDbDataSource datasource = new MariaDbDataSource();
      datasource.setUser("USER");
      datasource.setPassword("PWD");
      datasource.setUrl("jdbc:mariadb://localhost:3306/db?user=USER1");

      Connection will use user "USER1"


      recommended way to connect a pool is using Driver implementation, not DataSource
      example :
      final HikariDataSource ds = new HikariDataSource();
      ds.setMaximumPoolSize(20);
      ds.setDriverClassName("org.mariadb.jdbc.Driver");
      ds.setJdbcUrl("jdbc:mariadb://localhost:3306/db");
      ds.addDataSourceProperty("user", "root");
      ds.addDataSourceProperty("password", "myPassword");
      ds.setAutoCommit(false);
