[slf4j-user] Still getting log output when using slf4j-nop.jar

[Ceki Gulcu]

Hi Bart,

Well, when slf4j-api binds with a logging framework, it does so
completely. So either slf4j-nop is bound and you get no logs generated
by slf4j or slf4j is bound to another framework in which case you
would get many different logs from various sources. It really looks
like the "Fatal error" your are getting is not related to SLF4J nor
generated through it.

HTH,
