Remko Popma resolved LOG4J2-392.
--------------------------------
Resolution: Fixed
Fixed in revision 1602598.
The new solution brings back some code from a previous solution that keeps
track of the AsyncLoggerConfig instances that have been stopped to prevent the
same instance from being stopped more than once.
At the same time, the new solution still correctly clears the appenders for
_all_ LoggerConfigs, and still does this after all AsyncLoggerConfigs have been
stopped.
I verified that the AppenderOverwhelmer test still works correctly, and also
verified that the above NPE (premature Disruptor shutdown) problem no longer
occurs.
