title: Scala Actors in Scala 2.10 don't get recognized
body: <p>I recently updated to Eclipse Juno, which also updated my Scala to 2.10. I know that Actors are deprecated now, but I'd still like to use them. The scala-actors.jar and scala-actors-migration.jar are part of my Eclipse build path, however, I get "object actors is not a member of package scala" for the imports. Any tries to re-add the scala library to the project failed didn't fix it either.</p>
  
  <p>Mac OS X Lion with Eclipse Juno and Scala 2.10.</p>
  
  <p>Some code (Marked the errors XXX):</p>
  
  <pre><code>import scala.actors.Actor    XXX actors not found in scala
  import scala.actors.Actor._  XXX actors not found in scala
  
    class Solver() extends Actor {   XXX Actor not found
  
      def act() {
        // Read file
        val source = io.Source.fromFile("src/labyrinth.txt", "utf-8")
        val lines = source.getLines.toList
        source.close()
  
        // Fill multidimensional array
        var labyrinth = Array.ofDim[Cell](lines.length, lines.apply(0).length)
        for (i &lt;- 0 until lines.length) { // each line
          for (j &lt;- 0 until lines.apply(0).length) { // each column
            labyrinth(i)(j) = new Cell(lines.apply(i).toList.apply(j)) // Fill array cell with character
          }
        }
  
        // Search for start
        for (k &lt;- 0 until labyrinth(0).length) {
          if (labyrinth(0)(k).character.toString() == "?") {
            val start = new CheckCell(labyrinth, Array((1, k)), this).start // Kick off search
            while (true) {
              receive { XXX receive not found
                case FoundSolution =&gt;  XXX FoundSolution not found
                  Console.println("Pong: stop")
                  start ! Stop  XXX Stop not found
                  exit()
