title: activator or sbt start fails with Play 2.3
body: <p>I was trying to launch the Play Framework 2.3.4 server on Windows 8 with <code>avtivator start</code> or <code>sbt start</code>, and run into following errors:</p>
  
  <pre><code>The input line is too long.
  The syntax of the command is incorrect.
  </code></pre>
  
  <p>Because of the long CLASSPATH. But event with the newly created app I run into an error:</p>
  
  <pre><code>Bad application path: -Dhttp.port=9000
  </code></pre>
