The user manual refers to Commons-logging twice in its Binding with a logging framework at deployment time section, most importantly in its description of slf4j-jcl-2.0.7.jar:
Binding/provider for Jakarta Commons Logging. This binding will delegate all SLF4J logging to JCL.

While calling Commons Logging "Jakarta Commons Logging" may not be incorrect, it would be much better to call it "Apache Commons Logging", since it was renamed more than 13 years ago.

Note that despite this rename, the previous acronym "JCL" is strangely still used, so I would suggest to keep mentioning "Jakarta Commons Logging" or at least keep the acronym.

(By the way, in the last code example of the Fluent Logging API section, the "a" is missing insetMessge).
