当我编译以下内容时:

import org.junit.Test

class TypesTest{

  @Test
  def specializedTest(): Unit = {

    trait TTBase[@specialized T] {
      def evaluate:T
    }

    case class TTX[@specialized T](value:T) extends TTBase[T] {
      def evaluate:T = value
    }

    println( TTX(123).evaluate )
    println( TTX("s").evaluate )
  }
}

然后 scala 会出现以下错误。

如果将 TTBase 和 TTX 移至包范围,则可以正常编译。scala(2.11)的内部类中不允许专门化吗?
