> Master fails to build unless current snapshot log4j-core version is already

> To reproduce, execute {code} rm -r
> ~/.m2/repository/org/apache/logging/log4j{code} and invoke usual mvn clean
> install.
> This is because log4j-core has this dependency, which itself references
> log4j-core (with a defined version which gets correctly overriden by
> 3.0.0-SNAPSHOT).
