java.util.ServiceConfigurationError: java.sql.Driver: Provider org.h2.Driver not found in JBoss EAP 6

Issue

• We are getting this exception, we created a mysql module such as:

<module xmlns="urn:jboss:module:1.1" name="com.mysql">
    <resources>
        <resource-root path="mysql-connector-java.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.servlet.api" optional="true"/>
    </dependencies>
</module>

Then we configured our datasource as:

<subsystem xmlns="urn:jboss:domain:datasources:1.0">
      <datasources>
        <datasource jndi-name="java:jboss/MySqlDS" pool-name="MySqlDS">
          <connection-url>jdbc:mysql://localhost:3306/test</connection-url>
          <driver>mysql</driver>
          <security>
            <user-name>example-user</user-name>
            <password>example-password</password>
          </security>
        </datasource>
        <drivers>
          <driver name="mysql" module="com.mysql">
            <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
          </driver>
        </drivers>
      </datasources>
    </subsystem>

We are seeing this exception below at startup, where it looks like JBoss is looking for org.h2.Driver although we removed this from the configuration since we are using mysql.
