title: Use case for RuntimeException from package Kotlin
body: <p>I was writing some code and was going to throw a <code>RuntimeException</code> as a default for something, when I noticed that there are two options for <code>RuntimeException</code> - one from <code>java.lang</code> and one from <code>kotlin</code>:

  <p>Inside the kotlin version of this, there's an entire list of other methods which work the same way :</p>

  <p>So, from my understanding of this, the one from package <code>kotlin</code> is simply an alias for the java equivalent (correct me if I'm wrong) which leads me to the question : </p>
  
  <p>what is the point of having this alias file and when should you use it over the "standard" java equivalent ? Does this simply save a few imports ?</p>
