[slf4j-dev] slf4j 2.0.0-alpha6 still referring to log4j 1.x

Hi Team, We are trying to upgrade slf4j to the latest version 2.0.0-alpha6 <https://mvnrepository.com/artifact/org.slf4j/slf4j-api/2.0.0-alpha6>. We have noticed that it is still referring to log4j 1.x. We need to upgrade log4j version 2.x in our application. Looking for your support. Thanks, Vijay.
