When SLF4J can't load some class, it just says

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details

It would be very useful if it also printed out what classloader it used, and
from which class it was initialized (taking this info from call stack).

In modularized environments getting more used, this will become increasingly
important. Thanks for considering.
