When using the Spock Framework (http://spockframework.org/) in combination with slf4j.detectLoggerNameMismatch you get logger mismatch messages like this:

SLF4J: Detected logger name mismatch. Given name: "org.example.MismatchTest"; computed name: "org.slf4j.LoggerFactory$getLogger".
SLF4J: See http://www.slf4j.org/codes.html#loggerNameMismatch for an explanation

It seems that Spock does some magic with its test classes...
