scala中的对象初始化序列在固有层次结构中

我是 java的scala的新手,并且在固有的层次结构中被scala的对象初始化序列搞糊涂了. IIRC,在 Java中,如果初始化了子类的对象,则在其自己的构造函数的任何代码之前调用其基类的构造函数.在scala中,我的行为完全不同.请考虑以下示例：

class Point(val x: Int,val y: Int){
    val name = this.makeName;

    def makeName: String = {
        println("makeName at super.");

        "[" + x + "," + y + "]";
    }

    override def toString: String = name;
}

class ColorPoint(override val x: Int,override val y: Int,var color: String) extends Point(x,y) {

    // key statement
    println(name);

    override def makeName: String = {
        println("makeName at sub.");

        super.makeName + ":" + myColor;
    }

    val myColor = color;

    override def toString: String = name;
}

我们只考虑使用javap转储的ColorPoint构造函数的字节代码.如果代码包含关键语句println(name);字节码是

public ColorPoint(int,int,java.lang.String);
  Code:
   0:   aload_0
   1:   aload_3
   2:   putfield        #13; //Field color:Ljava/lang/String;
   5:   aload_0
   6:   iload_1
   7:   iload_2
   8:   invokespecial   #18; //Method Point."<init>":(II)V
   11:  getstatic       #24; //Field scala/Predef$.MODULE$:Lscala/Predef$;
   14:  aload_0
   15:  invokevirtual   #28; //Method name:()Ljava/lang/String;
   18:  invokevirtual   #32; //Method scala/Predef$.println:(Ljava/lang/Object;)V
   21:  aload_0
   22:  aload_3
   23:  putfield        #34; //Field myColor:Ljava/lang/String;
   26:  return

我们可以看到字段myColor在invokespecial之后初始化,即在初始化基类之后.

如果我注释掉语句println(name);字节代码是：

public ColorPoint(int,java.lang.String);
  Code:
   0:   aload_0
   1:   aload_3
   2:   putfield        #13; //Field color:Ljava/lang/String;
   5:   aload_0
   6:   aload_3
   7:   putfield        #15; //Field myColor:Ljava/lang/String;
   10:  aload_0
   11:  iload_1
   12:  iload_2
   13:  invokespecial   #20; //Method Point."<init>":(II)V
   16:  return

我们看到myColor字段在invokespecial之前初始化,即在base初始化之前.

那是什么原因？任何文件/文章都指明了这种行为？

顺便说一句,我的scala版本是2.7.7final(OpenJDK Server VM,Java 1.6.0_20).谢谢,最诚挚的问候！
