Comment 1 Greg Watson CLA 2008-10-24 16:06:36 EDT 
The problem occurs because the InputStream from HostShellProcessAdapter does not correctly handle the situation when the shell exits, instead it throws an IOException. As a workaround, I've merged HostShellProcessAdapter with RSEProcess and fixed this particular situation. In reality, this should be fixed in RSE.
