Typically, you can't use a 'new' operator on a generic type. This is because of type erasure.

scala> def create[T] = new T
<console>:7: error: class type required but T found
   def create[T] = new T
                       ^

Scala gives a way of getting around this problem, with the Manifest class.

scala> def create[T](implicit m:Manifest[T]) = m.erasure.newInstance
