Description

Within my organization, I've had to develop a custom appender that automatically configures certain properties and a specific layout to tie into other initiatives we have tied to logging. Log4j2 made this much more difficult than Log4j1 due to the use of final on many classes (e.g. the appender implementations) and methods (all pattern layout methods). This has made extension overly difficult and filled with a lot of copy and paste that I'd rather not have. Is it possible that these could be removed to make it easier to extend the existing implementations?
