[jira] [Commented] (OFBIZ-5287) Migrating from Log4j 1.2.17 to log4j2

[Nicolas Malin (Jira)]

    [ https://issues.apache.org/jira/browse/OFBIZ-5287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13729742#comment-13729742 ]

Jacques Le Roux commented on OFBIZ-5287:
----------------------------------------

While working on Solr integration OFBIZ-5042, I noticed that slf4j seems unused in OFBiz.

I believe it was introduced with JCR. Since JCR is now only in the jackrabbit20120501 branch, I think we can remove the libs.

If ever we need the facade again (to use another log system) we can always put it back...

> Mostly because of the introduction of  [LMAX Disruptor library|http://martinfowler.com/articles/lmax.html] in log4j 2, but not only, I want to upgrade log4j to [log4j 2|http://logging.apache.org/log4j/2.x/]
> [The migration does not seem too hard to do| http://logging.apache.org/log4j/2.x/manual/migration.html]. I found only usage of Appender when unloading containers and of course in
> Debug.java; Appender  and LoggerRepository  classes
> There is also [a easy to install bridge for SLF4J|https://loggapache.org/log4j/2.x/log4j-slf4j-impl/index.html]
> About LMAX Disruptor, [here is a brief introduction|http://stackoverflow.com/questions/6559308/how-does-lmaxs-disruptor-pattern-work],
> I discovered the usage of LMAX Disruptor in log4j2 [through this blog entry|http://www.grobmeier.de/log4j-2-performance-close-to-insane-20072013.html#.UepjvGTfxFo]
