There are many other places that have excessive logging as well in RichFaces We need to take a look at what can be moved to "TRACE", and what can be removed.
org.ajax4jsf.io.parser.FastHtmlParser] (http-127.0.0.1-8080-1) Parser reached state is StateManager.DOCTYPE
We used to have the clean up task for server side logging in the plan for 3.3.0 (http://www.jboss.org/auth/wiki/RichFacesWhatIsNewIn3_3_0 section 2) before the plan was changed.
I suggest it is still actual and should not be forgotten. Well designed logging (both server and client side) helps to reduce the time developers spend finding problems.
