[jitsi-dev] MediaStream.getRemoteDataAddress() returns null after MediaStream.start()

What would cause this to be null after a successful start?

Here are the steps leading up to the method call:

   - get MediaService instance
   - get MediaFormatFactory via MediaService instance
   - get Audio and Video device instances
   - create MediaFormat for audio and video using MediaFormatFactory
   - create SrtpControl via MediaService
   - create MediaStream for audio and video using MediaService with Device
   and SrtpControl parameters
   - add dynamic payload type to MediaStream instances
   - set direction to SENDONLY on MediaStream instances
   - set format on MediaStream instances
   - create a DatagramSocket for both rtp and rtcp
   - create InetSocketAddress for both ports on my public IP
   - create a StreamConnector for both audio and video
   - set StreamConnector on each MediaStream instance using DatagramSocket
   - create a single MediaStreamTarget using the InetSocketAddress
   - set MediaStreamTarget on both MediaStream instances
   - set names on MediaStream instances ("audio" / "video")
   - start SrtpControl with MediaType.AUDIO
   - start the audio MediaStream instance
   - start the video MediaStream instance

All of these actions complete without an exception and the following is
output into my log:

After all this completes, I call
InetSocketAddress audioAddr = audioMediaStream.getRemoteDataAddress();
and it always returns null; same for my video MediaStream.
