Hi guys, I try to understand Star-projections. 
I had simple interface on java. When I convert it to kotlin it used star-projection. 
When I try to assign one item of the List that is defined like List<*>, it forces me to cast. But when I cast it also gives warning about unchecked casting. When I try to check the type of the object it gives me error. 
Here is the code;

lateinit var address: List<Address>
override fun onTaskComplete(results: Map<Int, List<*>>) {
    address = results[0] as List<Address>
}

Here is the interface;
interface TaskListener {
    fun onTaskComplete(results: Map<Int, List<*>>)
}
