Subject Re: [crypto] Logging dependency
Date Thu, 09 Jun 2016 18:19:25 GMT
There is a huge list of advantages to using log4j-api over slf4j-api
nowadays, plus I do prefer to use Apache dependencies in Apache projects
unless the competition is clearly better for the use case (like using Jetty
instead of Tomcat in Karaf due to OSGi support). Also, using log4j-api
works fine with logback as well, so it's not like it prevents people from
using slf4j bindings at runtime.
