title: Kotlin (Mutable)List<(raw) kotlin.Any?> cast to List<JsonObject>
body: <p>in my code i get an io.vertx.core.json.JsonArray and i want to have a List of JsonObjects. 
  So in Java i called jsonarray.getList() and get List - getList() returns a java.util.List.</p>
  
  <p>So in Kotlin</p>
  
  <pre><code>var list: List&lt;JsonObject&gt; = jsonArray.getList()
  </code></pre>
  
  <p>but i get an error</p>
  
  <pre><code>Type mismatch: inferred type is kotlin.collections.(Mutable)List&lt;(raw) kotlin.Any?&gt;! but kotlin.collections.List&lt;io.vertx.core.json.JsonObject&gt; was expected
  </code></pre>
  
  <p>Can i cast or so?</p>
  
  <p>Thx</p>
