Read only property fail the null check

1 


public data class Feed(public val rss : Rss?, public val atom : Rss?){
    public var title : String = ""
    public var language : String = ""
    public var feedType : FeedType = FeedType.NONE
    public var items : ArrayList<Item> = ArrayList<Item>()



  fun transformRss()

  {

  if (rss != null){

            title = if (rss.channel!!.title == null) “” else rss.channel!!.title!!

            language = if (rss.channel!!.language == null) “” else rss.channel!!.language!!

            feedType = FeedType.RSS


            for(val i in rss.channel!!.item!!.iterator()){

            }

  }

  }

generates compilation error although I did check rss != null inside transformRss. The compiler insists that I do ensure on rss!! property.

This is not exactly a bug, but this can be improved. The problem is that the properties are public. The special case here is that we are in the same class (and thus the same module), so them being public doesn't make them potentially changable.
