[keycloak-user] Keycloak slf4j logging

Hi, Is there any request or effort to let keycloak use slf4j? At the moment ClientCredentialsProviderUtils calls org.jboss.logging.Logger.debugf(Ljava/lang/String;Ljava/lang/Object;Ljava/lang/Object;)V which does not seem to exist in JBoss 4.2.3.GA, and causes a NoSuchMethodError.
