title: ClassCastException: org.slf4j.impl.Log4jLoggerAdapter cannot be cast to ch.qos.logback.classic.Logger
body: <p>I was following <a href="https://stackoverflow.com/questions/5448673/slf4j-logback-how-to-configure-loggers-in-runtime#answer-5715581">this</a> answer in order to add a appender on runtime. Even though that works for the original poster, I get this exception in line <code>Logger logger = (Logger) LoggerFactory.getLogger("abc.xyz");</code>:</p>
