There's already this installed: <driver module="com.h2database.h2"/> and that results in the driver service already being present. I'll let Jesper, Stefano or John Bailey comment on whether there's any reason to have the 'driver="com.h2database.h2"' parameter to that operation, rather than just requiring the name of the resource to be the name of the module: /profile=default/subsystem=datasources/jdbc-driver=com.h2database.h2:add You still wouldn't be able to add the module twice, but at least the reason why not would be clear.
