JBoss EAP support for MariaDB started on version 7.0 so your version is not a problem.
From the error WFLYJCA0040: failed to invoke operation: WFLYJCA0042: failed to match pool. Check JndiName, and assuming the jdbc name is correctly assigned, I believe your issue will be solved on step 1.3 and 2, as below:
When setting up a data source on JBoss EAP 7.0:
deploy the driver
create the datasource
Verify the pool size, removing the line <max-pool-size>0</max-pool-size> as explained here.
reload
For your version, JBoss EAP 7.0 : Remember to enable the DB:
#/subsystem=datasources/data-source=MyExampleDS:enable()
#/subsystem=datasources/data- source=MyExampleDS:test-connection-in-pool()
