I have recently started a discussion<https://community.jboss.org/message/558408#558408> about the use of Static versus Transient Logger declarations in open source libraries that are intended to be used in multiple application containers (or other contexts) after reading the following Apache Commons Logging article:
Logging/StaticLog http://wiki.apache.org/commons/Logging/StaticLog The article seems sound to me, and does a good job of explaining why Transient is generally the better strategy, should not cause any tangible performance degradation with most modern logging libraries, and more importantly, why it will actually work correctly when used in anything but the simplest Java application. However, some people have responded to this thread by either focusing on performance (which seems to be a mute point in my opinion) or by focusing on the features of one specific Logger library implementation. Both perspectives seem to be short sited if you are intending to create a library that can be used in any context (e.g., any application container, application, used by another library, etc). I am asking for participation from the Apache community because some replies have (politely) discredited or dismissed the Apache article that I referenced. If the article is in fact out of date, then can someone please verify that, and amend the Apache Commons Wiki? If the article is not outdated, and is still technically accurate, then can someone who is intimately familiar with this topic step forward and help defend the position, and educate others who might be interested in this topic? I would like to see the correct strategy employed in future work by this community (and other open source communities) because many open source libraries are incubated under bigger projects like JBoss AS, but intended to be used more widely as well. I would hate to see the incorrect pattern being proliferated just because it is the "de facto norm" especially if there is an opportunity to help educate everyone about a better approach. So in summary, I am asking for help getting facts (not opinions) communicated about Static versus Transient Logger declarations, so developers who are creating libraries that are intended to be used in any context (any application container, etc), can have a solid reference about which strategy is best. Again, for easy reference, the link to the forum discussion is: Better strategy for instantiation of Logger instances (static causes problems) https://community.jboss.org/message/558408#558408 Thanks in advance to anyone who participates!
