動態特徵NoSuchFieldError @ 2.9.0RC4

Question

以下是一個錯誤還是故意的？

trait Dyn { 
    val D1 = new Dynamic { 
    def applyDynamic(name: String)(args: Any*) = "Hi" 
    } 
    object D2 extends Dynamic { 
    def applyDynamic(name: String)(args: Any*) = "Hey" 
    } 
} 
trait T { self: Dyn => 
    def foo1 = D1.X 
    def foo2 = D2.X 
} 
object T extends T with Dyn 
object Dyn extends Dyn 

T.D1.X // works 
Dyn.D1.X // works 
T.foo1 // doesn't work: java.lang.NoSuchFieldError: reflPoly$Cache1 

T.D2.X // works 
Dyn.D2.X // works 
T.foo2 // works
