title: FlexUnit ANT task is hanging
body: <p>I'm using the ANT task to run FlexUnit on a build server. When I run the Flex Unit Tests from the Flash Builder (4) it works fine. But when running from ANT it opens the default player (FireFox in my case), runs the FU successfully but never returns to the command line. Eventually I get a "<em>java.util.concurrent.ExecutionException: Socket timeout waiting for flexunit report</em>" exception because the FU never returns. </p>
  
  <p>What could be the problem?</p>
  
  <pre><code>&lt;flexunit swf="${APP_TEST_FILE_SWF}"

  haltonfailure="true" verbose="true"
