Subject Re: log4j2 how to write a wrapper that passes the class name of my own
Date Sun, 02 Nov 2014 11:22:14 GMT
I see that the generated class casts the Logger to AbstractLogger to get
the ExtendedLogger, is this always the case? I know that logger classes
should extended AbstractLogger and not just implement Logger, but how can
we be sure?
