> Log4j 1.x went EOL in August 2015. JDK 9+ support (KNOX-1458) will require Log4j 2 since Knox uses MDC for all the audit logging. More details about the issue and migration are found here:
>  * [https://blogs.apache.org/logging/entry/moving_on_to_log4j_2]
>  * [https://logging.apache.org/log4j/2.x/manual/migration.html]
> Items of "concern"
>  * MDC migrate to ThreadContext
>  * log4j.properties need to migrate to log4j2.xml (or yaml or json)
> Benefits
>  * Async logging
>  * Dynamic reloading of configuration changes
