-LOG4J2-265: FlumeAppender Stops App from Shutting Down when Newer Version of Netty is Used
Make you aware of this work item raised against LOG4J2:
Ralph from Log4j2 thinks it's a Flume issue so I've asked the reporter to
retest against 1.4 (because it looks like Flume-2002) and raise the issue
against Flume if it repros.
