FlexUnit CIlistener problems after upgrade to 4.5

Hello,

   I've just upgraded to Flash Builder 4.5 and I'm getting this error when I'm running test from my ant build:

java.util.concurrent.ExecutionException: Socket timeout waiting for flexunit report

Usually, this is because the CIListener is not added to the test suite but I'm using it as you can see here:

                                        core = new FlexUnitCore();

                                        core.addListener(new CIListener());

                                        core.addListener(new UIListener(uiListener));

                                        core.run(testSuite.TdmseTestSuite);

I'm searching everywhere for a solution but no dice so far.

Please help!!
