CI issues on Linux - CentOS + Hudson

Question

Hi there,
I got some issues to generate the Junit reports, it gets up to "Waiting for client connection" then do nothing for a few seconds.
When it gets back this is what I get in the console:
runUnitTests:
     [java] Loading configuration file /opt/flex/frameworks/flex-config.xml
     [java] Failed to match the compile target with /root/.hudson/jobs/myProject_Continuous_Build/workspace/trunk/bin/TMCV6TestRunner.swf.cache. The cache file will not be reused.

It halts there unless I cancel the build, in that case I get the following in the console:

I'm using CentOS and Hudson.
Any help will be appreciated.
Thanks in advance,

Hi Brian,
Many thanks for your reply,
I'll reply inline:
- Make sure that you add the CIListener class to the core as a listener so this handshake can take place from the Flash movie.
This is how my Main file looks like:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                                xmlns:flexUnitUIRunner="http://www.adobe.com/2009/flexUnitUIRunner"
                                creationComplete="creationCompleteHandler()">
        <mx:Script>
                <![CDATA[
                        import org.flexunit.listeners.CIListener;
                        import au.com.infomedia.tmcV6.TMCV6Suite;
                        import au.com.infomedia.V6.V6Suite;
                        import org.flexunit.listeners.UIListener;
                        import org.flexunit.runner.FlexUnitCore;
                        private var core:FlexUnitCore;
                        public function creationCompleteHandler():void
                                core = new FlexUnitCore();
                                core.addListener(new CIListener());
                                core.addListener(new UIListener(uiListener));
                                core.run(V6Suite, TMCV6Suite);
                ]]>
        </mx:Script>
        <flexUnitUIRunner:TestRunnerBase id="uiListener" width="100%" height="100%" />
</mx:Application>
- Make sure that the X-Windows is installed and that you are able to launch the flash player using the gflashplayer symlink while logged in under the windowing environment.  Typically not having the correct dependencies installed will result in a Segmentation Fault error from my experiences.
I run vncserver and viewer by command line and I'm able to run gflashplayer inside the window.

- Try attaching to display :99 with a vnc client to see if an error message is being output and if the FP is opening before the server timeout occurs. This may have more clues to help.
I'm pointing to display :99 in Hudson, but you made me wonder, should Hudson open up the standalone player as Windows does, or it should run in the background as a different process?
I already tried setting up localTrusted and headless to true and false.
This is the ANT target I'm using to run the unit tests:
