Let's consider this code :

package io.gatling.recorder.scenario

import org.specs2.mutable.Specification
import org.specs2.runner.JUnitRunner
import org.junit.runner.RunWith

@RunWith(classOf[JUnitRunner])
class ScenarioSpec extends Specification {

}

This code compiles and has no unnecessary import.
The problem is that if I press "ctrl-shit-o", then, Scala-IDE removes the following import

import org.specs2.runner.JUnitRunner

And then, the code can no longer be compiled :-/
