Just a quick fix to a problem I ran into, putting it out there just in case it helps someone. Ignore this post if you haven't run into this exception.
While configuring logback in order to filter out a bunch of redis.actors.RedisClientActor messages (tangential note: rediscala WTF?) I ran into the following error:
Failed to instantiate [ch.qos.logback.classic.LoggerContext]
Reported exception:

Turns out that to use the ch.qos.logback.core.filter.EvaluatorFilter (which allows you to filter log messages by regex), you need to include the following dependency in addition to logback:
"org.codehaus.janino" % "janino" % "2.6.1"
<dependency>
<groupId>janino</groupId>
<artifactId>janino</artifactId>
<version>2.5.10</version>
</dependency>
(Take your pick whether you prefer sbt or maven.)
You can also suppress rediscala log messages by putting:
rediscala {
loglevel = "ERROR"
}
into your application.conf.
Just putting this on the interwebs in the hope someone finds it useful.
