A strange bug when use InPutStream and OutPutStream

[evermuteman]

I am tring to use jsch implementing a webssh recently, but i found that when i tried to use Stream something strange happens

Here is my test code

I am sure it connects successfully

But when i send command to remote server, not only the results are sent to me back, but also the previous command i sent

I sincerely thank your attention, this really makes me confused.
