title: Coroutines in Java
body: <p>I am reading this page about <a href="http://www.informit.com/articles/article.aspx?p=2320938" rel="noreferrer">coroutines in Python</a> and this <a href="https://en.wikipedia.org/wiki/Coroutine" rel="noreferrer">Wikipedia page.</a> I saw that there are a few <a href="https://stackoverflow.com/questions/2846428/available-coroutine-libraries-in-java">libraries in Java</a> implementing coroutines. </p>
  
  <p>My question is: is there any known reason why the Java designers decided not to implement coroutines so far and is there any plan to include it in a future version of Java?</p>
  
  <p>Thanks.</p>
