Re: [xwiki-devs] [Proposal] Switch from Commons Logging/Log4j to SLF4J/Logback

Hi, I'd like to propose switching from Commons Logging/Log4j to SLF4J/Logback for the following reasons: * slf4j was written to solve the issues with commons logging (memory leaks under some circumstances). http://www.google.fr/search?aq=f&sourceid=chrome&ie=UTF-8&q=slf… * logback is the successor of log4j and addresses the following when compared to lgog4j: http://logback.qos.ch/reasonsToSwitch.html * New stuff happens in logback and not in log4j * I'd also like to switch to logback since it has full-fledged JMX support which allows us to easily change logging configuration at runtime (changing log levels for example): http://logback.qos.ch/manual/jmxConfig.html Note that migrating a log4j.properties file is easy: http://logback.qos.ch/translator/ In addition if a user wants to stay on log4j it would be possible and easy: simply remove the logback jar and replace it with the slf4j-log4j one. WDYT? Thanks -Vincent
