When trying to run FMJ-Studio and setting up a RTP transmission there is a nullpointer in src.rtp.net.sf.fmj.media.rtp.RTPSessionMgr.java line 624 [socket = new RTPSocketAdapter(localAddress.getDataAddress(),
localAddress.getDataPort(),
localAddress.getTimeToLive());]because the field localAddress is set nowhere. It is not even described what localAddress expresses.
