akka.exlude doesn't work

[stasimus]

Inside the agent.conf

I put this

org.eigengo.monitor.agent {
output {
class: "org.eigengo.monitor.output.codahalemetrics.MetricsCounterInterface"
}

akka {
        excluded: [ "akka://*/user/*"]

        includeRoutees: false
        allowExclusions: false
    }

}

but still all actor metrics under akka://mysystem/user/* are collected. Unfortunately I have to use exclude, because monitor kill all 24 processor cores.
