title: IntelliJ keeps displaying annoying message: Unable to open debugger port (127.0.0.1:56568): java.net.BindException "Address already in use"
body: <p>I am writing a simple JAR application in IntelliJ. When I debug it for the first time, it works without any problem. But when I try to debug a second time, I get this annoying message:</p>
  
  <pre><code>Unable to open debugger port (127.0.0.1:56568): java.net.BindException "Address already in use"
  </code></pre>
  
  <p>If I wait for sometime and then try again, it works. Is there any way I can fix this?</p>
