Hi [~ggregory] 

Really appreciate your input on this, it makes sense and the work around does work fine.

However modifying the jar manually will not be an apt solution for us as we have multiple applications and environments and it might be not possible to maintain a custom version for log4j-api alone. It will be prone to errors.

Kindly check on this, Thank you.

FYI Tomcat VERSION:-8.0.23

Regards
