    Description

      Assigning to version 1.2.0 to have a discussion about it.

      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:

      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
