(As I mentioned previously) SLF4J is yet another logging framework that you have in your configuration. It is a competitor of Apache Commons Logging, a facade for log4j or other logging framework. http://www.slf4j.org/ It is explained on their site about that "Class path contains multiple SLF4J bindings." warning that when several conflicting implementations for slf4j are available, the first found wins. The first one mentioned is logback-classic.jar http://logback.qos.ch/ Logback is yet another logging framework, at the level of log4j. You have no configuration file for it, so apparently what you get is its default configuration. (Just from code it seems that their root Logger has level of DEBUG by default). Maybe you started to use classes that depend on slf4j and thus the library had to initialize itself.
