> In InvertedShellWrapper, pumpStreams() method first checks if the process is
> alive, and only then pumps streams. It could happen that after the process
> has already exited, some information is left out in out or err streams.
> Moving the check for shell.isAlive() after all pumpStream() calls seems to
> resolve the issue.
> I've uploaded a patch for your convenience here
> https://gist.github.com/1206056
> steps to reproduce:
> 1. create a default server
> 2. set command factory as described at http://mina.apache.org/sshd/tips.html
> 3. run `ssh localhost -p 8000 echo test`
> expected result:
> command output is `test`
> actual result:
> usually nothing is printed even though the command is executed
