Java expect. Library selection. Is it possible to run in multi-threaded mode?

Question

Java

Good day.
Linux has a wonderful expect tool, which I have repeatedly used to query network equipment via telnet and ssh protocols.
I found several java implementations of this utility, each of which theoretically would also solve similar problems.
However, there are many network devices, there is little time, and I would like to parallelize this task.
Perhaps someone will advise an expect-like library that would work safely in multithreading mode?
Specifically, I'm quite new in Java, so I would also be grateful for a warning about possible pitfalls.
PS. Yes, I know that there is SNMP and we use it for most devices. Simple and tasty, but nevertheless, there are still a lot of pieces of iron that are available exclusively via ssh and telnet.
Thank you.

Answer 1

If ssh to Java or Ant then choice number 1 is www.jcraft.com/jsch

Answer 2

Thanks for answers.
I will test.
I wanted exactly something like expect, because spawn telnet + spawn ssh looked very tempting in one bottle.
You may have to run each of the protocols with your own library.
