FlexUnit + AIR + Ant: flashplayer hangs

Hi,

I'm currently experiencing some issues when trying to run FlexUnit tests with Ant and AIR. The player doesn't close after the tests are finished and it's giving me the following error when I kill the player:

You can download the testproject from here which should reproduce the issue: https://docs.google.com/open?id=0BwgTrjDn2SAhSmhkWmlQbFlXQ0k

I'm running on Windows 7 64-bit, using Flex 4.6
