[logback-user] Verbose startup output

[Ceki Gulcu]

Hell Noam,

Logback internal messages, aka status messages, come in 3 flavors, INFO, WARN 
and ERROR. There is no DEBUG level. From what I could gather from the messages 
you included, in particular in relation to the "debug attribute" as emitted by 
ConfigurationAction, it looks like somewhere in your application, you are 
explicitly invoking StatusPrinter to print out logback's internal messages.

Look for code invoking StatusPrinter.print() in your code.
