Review comment:
Thanks @keith-turner - this is actually a [published](https://logging.apache.org/log4j/2.x/security.html) and accepted mitigation per the log4j team themselves. I don't think it is worthwhile trying anything else out given the ELK stack is completely unrelated to our primary focus here in Accumulo.
