2.8.0 and explicit implicit import fails

[Blair Zajac]

Using r19410 importing a single implicit def fails:


scala> import scala.collection.JavaConversions.asMap
import scala.collection.JavaConversions.asMap

scala> val sm : scala.collection.Map[Int,Int] = new java.util.HashMap[Int,Int]
<console>:5: error: type mismatch;
  found   : java.util.HashMap[Int,Int]
  required: scala.collection.Map[Int,Int]
        val sm : scala.collection.Map[Int,Int] = new java.util.HashMap[Int,Int]


but importing all the implicits works:


scala> import scala.collection.JavaConversions._
import scala.collection.JavaConversions._

scala> val sm : scala.collection.Map[Int,Int] = new java.util.HashMap[Int,Int]
sm: scala.collection.Map[Int,Int] = Map()


Is this a bug?

Could this be due to the fact that there are two asMap's defined in
scala.collection.JavaConversions?

Regards,
Blair

After chatting on IRC, Paul Philips also thought that this may be a  
bug, so I opened:
