title: Alternative to sun.misc.Signal
body: <p>I started research to find an alternative to the <code>sun.misc.Signal</code> class, because it could be unsupported in upcoming JDKs (we're currently working on 1.6). When I build the project I get:</p>
  
  <blockquote>
    <p>warning: sun.misc.SignalHandler is Sun proprietary API and may be
    removed in a future release</p>
  </blockquote>
  
  <p>I came across multiple solutions but they don't fit my project e.g. in <a href="https://stackoverflow.com/questions/5023520/sending-signals-to-a-running-jvm">this question</a>.</p>
  
  <p>This is unacceptable in my situation because:</p>
  
  <ul>
  <li>Signals are used not only for killing application</li>
  <li>The application is huge - every conceptual change of communication between modules/JVMs could take years to implement</li>
  </ul>
  
  <p>Thus, the desirable solution is to find something like a new Oracle version of this class or something which works in the same way. Does such a solution exist?</p>
