Remko Popma commented on LOG4J2-703:
------------------------------------

Nelson, I created LOG4J2-716 to follow up on the JMX issue. 

If you know more about whether JMX is supported or not and perhaps give some sample code for
making JMX work on Android that would be much appreciated! In that case please add comments
to LOG4J2-716.
