title: cannot convert from String to Integer
body: <p>I have implemented some service which works fine. The service has the following property:</p>
  
  <pre><code> @Property(name = MyService.PROXY_PORT, label = "Proxy Port", description = "Proxy Port", value= "8080")
      private static final String PROXY_PORT = "proxy.port";
  </code></pre>
  
  <p>I get the value of the <code>port</code> property as follow:</p>
  
  <pre><code>..
  ...
  properties = context.getProperties();
  String port = properties.get(PROXY_PORT).toString();
  ...
  </code></pre>
  
  <p><code>port</code> in this case results <code>8080</code>. Now I would like to convert this String to Integer. I tried the following: </p>
  
  <pre><code>int portInt = Integer.parseInt(port);
  int portInt2 = Integer.getInteger(port);
  </code></pre>
  
  <p>Both results null :(</p>
  
  <p>What did I do worng?</p>
