Ceki Gulcu resolved LBCLASSIC-49.
---------------------------------

    Fix Version/s: 0.9.12
       Resolution: Fixed

The getLogger() method in LoggerContext class will now throw an IllegalArgumentException when invoked with a null argument.

I think that is the best logback-classic can do, since a null name argument is illegal. LoggerContext.getLogger(null) has to return something but can't...
