Error starting spark-jobserver with Apache Spark 2.0.2 - apache-spark

Question

I'm trying to start the spark-jobserver. I can't find any reference to this akka library on the installation steps provided on the GitHub spark_jobserver page.
I'm running spark in standalone mode on a single server which act as a master/node.
But when I execute
./job-server/server_start.sh
it shows the following error:
error while starting up loggers

Two steps to solve this issue:
The spark-job-server.jar created after execute ./bin/server_package.sh < enviroment> it have to be moved to the jars folder located on $SPARK_HOME
Nevertheless I had to download akka-slf4j_2.11.0-RC3-2.3.0.jar and put it on the $SPARK_HOME/jars folder too.
