Upgrading from Log4j to Log4j2: Dealing with Configuration Pitfalls and Asynchronous Logging Misconceptions
The author recounts attempting to upgrade from Log4j to Log4j2 due to lack of asynchronous support, discovers that Log4j2 does not accept properties files, switches to XML configuration, and eventually realizes asynchronous logging may not be necessary, illustrated with a screenshot.
Yesterday I tried to upgrade Log4j to Log4j2 because Log4j does not support asynchronous log storage.
I ran into a big pitfall: Log4j2 does not support properties‑based configuration, so I chose the XML method; fortunately I found a relatively comprehensive article and am still experimenting.
Later I realized that I might not actually need asynchronous logging after all!!!
