Currently the latter is common with `log4j-core`, but there is no reason for it to be this way. For example if `log4j2.simpleLogShowContextMap` is set to `false` (default), the `ThreadContextMap` should probably be a no-op. ########## src/site/antora/modules/ROOT/pages/manual/api.adoc: ########## @@ -220,7 +221,25 @@ link:../javadoc/log4j-api/org/apache/logging/log4j/LogManager.html[`EventLogger` xref:manual/eventlogging.adoc[Read more on event loggers...] -[#feature-fluent-api] +[#simple-logger] +=== Simple logger + +Even though Log4j Core is the reference implementation of Log4j API, Log4j API itself also provides a very minimalist implementation: _Simple Logger_. +This is a convenience for environments where either a fully-fledged logging implementation is missing, or cannot be included for other reasons. +`SimpleLogger` is the default Log4j API implementation if no other is available in the classpath.
