The Cocoon project is starting to move away from Avalon. Their "building on stone" email thread today , deals with the need to build Cocoon on a solid framework they have control over, and not on the framework of another team that is apparently suffering from high turnover ). Cocoon is higher-level than FOP , so I think what's true for them is doubly true for us.
So the vote is actually if we should use Avalon at all and not just about logging. If we drop Avalon (my knowledge about it is quite
limited so others (Jeremias/Joerg) will hopefully comment on it) then
commons-logging makes sense.
