FlexUnit Ant task freeze at Reciving Data...

Question

Hello,
I'm trying to use flex unit task and when I run it, get this on console and stay there for ever.
"*****" is just to privacy
this is my ant task
<target name="UNIT TEST">
                    <echo>COMPILING TEST SWF..</echo>
                    <mxmlc output="${basedir}/bin/Test.swf" file="${basedir}/test-src/TestRunner.as">

I still have not been able to get FlexUnit running with AIR SDK 15. But I found a workaround:
Compile the source code with SDK 15 into swc files.
Set FlexUnit to use SDK 4.
Do not include source code in the FlexUnit Ant task.
Include the swc files in stead by adding another library dir parameter to the flexunit call.
