min yun law commented on SSHD-1112:
-----------------------------------
without waitFor(), I get exception "Pipe closed after 0 cycles" when try to
read inputstream.
I will try a new thread only for readinputstream, and keep waitFor() as in main
thread

> Collection<ClientChannelEvent> waitMask = channel.waitFor(
> EnumSet.of(ClientChannelEvent.CLOSED, ClientChannelEvent.EXIT_STATUS,
> ClientChannelEvent.EXIT_SIGNAL, ClientChannelEvent.EOF),
> 0L //no TIMEOUT status returned if 0L
> );

> InputStream in = channel.getInvertedOut();
> String outputStr = "";
> if(in != null)
> {
> outputStr = readStream(in); //this is place that get stuck and exception is
> thrown
> }
> return outputStr;
> }

> String readStream(InputStream inputStream)
> {
> String line = null;
> String m_cmdOutput = "";
> try (BufferedReader bufReader = new BufferedReader(
> new InputStreamReader(inputStream)))
> {
> while ((line = bufReader.readLine()) != null)
