title: eclipse sts cannot start tomcat: ports already in use
body: <p>Tested eclipse indigo, STS 2.5.2, STS 2.8.0, STS 2.8.5.
  Tomcat 6, Tomcat 7.</p>
  
  <p>Tomcat startup hangs at 23%(displayed at right bottom side of eclipse windows/screen). This magic number is always the same. After about 20 seconds at hanged state error occurs.
  Error info is "ports are already in use".</p>
  
  <p>There is no Tomcat already started in system. No ports with specified numbers appear in netstat.</p>
  
  <p>Changing port numbers does not help anything.</p>
  
  <p>Changing/reinstalling eclipse,STS,tomcat, downloading fresh tomcat zip changes nothing.
  Deleting workspace and C:/Project/.metadata and stuff - all directories used by fresh install of STS, so deleting them does not help too.</p>
  
  <p>And interesting history aspect: i've used STS 2.8.2 for 2 weeks before this error occured. Reinstall won't fix anything. After that i was able to use STS 2.5.2 for a month. And the same error occured for 2.8.2. But i delete all its files and reinstall again does not fix anything.</p>
  
  <p>Reboot does not help.</p>
  
  <p>Have no any other working with tomcat version of eclipse/STS.</p>
  
  <p>Any help is appreciated.</p>

  <p>my os is windows 7. In Virtualbox XP everything is fine. And other Windows 7 guys say it works too on their PCs.</p>
