What steps will reproduce the problem?
1. Run code from 
http://code.google.com/p/gstreamer-java/wiki/BusMessageTutorial modified to use 
URI to a stream rather than input file. Example code: 
http://pastebin.com/j0epCC9y
2. Kill the internet connection and wait for the buffer to empty.
3. Music will now stop without the java program noticing.

What is the expected output? What do you see instead?
Pause/buffering indications (at least some kind of response) from either 
Bus.STATE_CHANGED, Bus.ERROR or Bus.EOS.

Have you tried to verify this is a gstreamer-java specific issue, and not a
problem with the gstreamer framework itself?
Running "gst-launch-0.10 playbin2 uri=..." from the command line and disabling 
the internet _does_ result in a PAUSE/Buffering message, so the error can most 
likely be found in the java-bindings.

What version of the product are you using? On what operating system?
Tried both the 1.5 jar and a svn clone from 26-sept 2012. Debian 6. GStreamer 
0.10.30.
