access of scala.collection.mutable.Stack[T] from Java

Dear all,
having a Scala library using Stack[T] (of scala.collection.mutable, not java.util) as method parameter (of a trait SearchProblemT[T <: ActionT[T]]), I would like to access this code from Java – unfortunately, scala.collection.mutable.Stack<T> does not seem to be the solution.
Does anybody know where the issue of accessing Scala container types from Java is covered?
Thanks a lot in advance, Nick
