title: Comparison of Java reactive frameworks
body: <p>I see many frameworks/libraries that claim that they can help build reactive applications in Java, such as: Akka, Vert.x, RxJava, Reactor, QBit, etc.</p>
  
  <p>They seem to have different approaches, features, pros, cons, etc. I could not find detailled comparisons. There is documentation about each of these framerwork, but it is not enough for me to understand the differences.</p>
  
  <p>What are the differences between the major Java reactive frameworks?</p>
  
  <p>And what are the application requirements that can drive the choice of a Java reactive framework?</p>
  
  <p>Thank you for your time.</p>
