Yes, the current situation is a (big) mess. > What I'm proposing is to gradually cut down to one logger API > ( commons-logging ) and the 2 major implementations ( log4j and > jdk1.4 ) and the associated ( and well-documented/well known ) > config files. > > This may take a long time, but there are few steps that we > can ( should ) take for the next releases ( 4.1.0 and 3.3.3 ). > Most of those are cosmetic ( i.e. minimal code changes ): > > 1.

It will take time, it will probably be painful to do, but it looks like the (only) way to go.
