Unable to connect WSO2 API Manager to MariaDB - mysql

Question

I tried to change the WSO2 APIM default datastore from H2 to MariaDB.
I followed the instructons at: https://apim.docs.wso2.com/en/latest/install-and-setup/setting-up-databases/changing-default-databases/changing-to-mysql/
I installed MariaDB on my system:
Server version: 10.4.12-MariaDB-1:10.4.12+maria~bionic mariadb.org binary distribution
I created 2 databases:
mysql> create database WSO2_MARIA_DB;
mysql> create database APIM_DB;
I created the tables in the 2 databases:
$ mysql -u root -p -DWSO2_MARIA_DB < '<WSO2_HOME>/dbscripts/mysql.sql';
$ mysql -u root -p -DAPIM_DB < '<WSO2_HOME>/dbscripts/apimgt/mysql.sql';
I copied mysql-connector-java-5.1.48.jar and mariadb-java-client-2.6.0.jar java connectors to /repository/components/lib
I changed the configuration in /repository/conf/deployment.toml to:
[database.apim_db]
type = "mariadb"
url = "jdbc:mariadb://localhost:3306/APIM_DB"
username = "root"
password = "*********"
pool_options.maxActive = 50
pool_options.maxWait = 30000
driver="com.mysql.jdbc.Driver"
[database.shared_db]
type = "mariadb"
url = "jdbc:mariadb://localhost:3306/WSO2_MARIA_DB"
username = "root"
password = "*********"
pool_options.maxActive = 100
pool_options.maxWait = 10000
pool_options.validationInterval = 10000
driver="com.mysql.jdbc.Driver"
When I start the wso2server I get the following error:
ERROR - DatabaseUtil Database Error - Unable to load class: com.mysql.jdbc.Driver from ClassLoader:org.eclipse.osgi.internal.loader.EquinoxClassLoader#5d32515d[jdbc-pool:9.0.16.wso2v1(id=90)];
