title: issue with GWT eclipse plugin
body: <p>i keep having an issue with GWT eclipse (helios) plugin in Linux box (opensuse 11.4).</p>
  
  <p>sometimes if i stop the dev mode server and then try "Run as-> web Application" it gives me the below error. sometimes this doesn't give error and the dev mode app is started by the gwt eclipse plugin.</p>
  
  <p>maybe the dev mode server remains running for sometime after i stop it with red button at right of "development mode" view tab. any Idea what this problem is about?</p>
