>  
> Here is sample code:
> String getExecCommandResult(ClientChannel channel)
> {
>         channel.open().await();
>         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)
>  {
>  m_cmdOutput += line + Constants.getDelimiter();
