Method in sealed trait gives Duplicate field name & signature in class file

[Dimitris Kouzis - Loukas]

Hello,

I don't know exactly how to accurate describe this, but I think it should be working and it doesn't. It fails on every Scala version I've tried certainly  2.10.5 and 2.11.7 (see here). I've also talked about it in SO.

scala>   def t4() = {
     |
     |     sealed trait IntList {
     |       def process (baseCase: Int, f: (Int, Int) => Int): Int =
     |         this match {
     |           case End => baseCase
     |           case Cons(hd, tl) => f( hd, tl.process(baseCase, f))
     |         }
     |
     |     }
     |
     |     final case object End extends IntList
     |
     |     final case class Cons ( hd: Int, tl: IntList) extends IntList
     |
     |     val l1: IntList = Cons(1, Cons(3, Cons(5, End)))
     | }
t4: ()Unit

scala> t4()
