> Explicit class casting makes integration with other libraries impossible.
> I've been trying to get a workaround but it seems I cannot do anything. The
> problem is in the Qpid library. Specifically Broker class line #147. Here's
> the full stack trace:
> {code:java}
> [info] Exception encountered when attempting to run a suite with class name:
> com.github.gvolpe.fs2rabbit.Fs2RabbitSpec *** ABORTED ***
> [info] java.lang.ClassCastException: org.slf4j.helpers.SubstituteLogger
> cannot be cast to ch.qos.logback.classic.Logger
> [info] at org.apache.qpid.server.Broker$1.run(Broker.java:147)
> [info] at java.security.AccessController.doPrivileged(Native Method)

> {code}
> The simple solution would be to avoid the unnecessary casting. Now this is
> happening on line 147:
> {code:java}
> ch.qos.logback.classic.Logger logger =
> (ch.qos.logback.classic.Logger)
> LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
> {code}
> Simple fix:
> {code:java}
> org.slf4j.Logger logger = LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
> {code}
