Dan Tran updated WAGON-431:
---------------------------
Description:
When the remote execution has stdout output > 32K ( hardcoded by jsch)
CommandExecutorStreamProcessor hangs waiting for remote stderr end of stream
which never arrive since remote shell is blocked by 32 buffer filled by stdout
The solution is process stdout first ( instead of stderror), however we may
encounter the same issue if stderr output is more than 32K which less likely to
occur than stdout
May be better to use StreamPumper from PlexusUtils to prevent blocking
