I posted related bug https://issues.jenkins-ci.org/browse/JENKINS-20128 and was fixed in 1.540. I decided to upgrade both our build servers (1 in our local network and other is remote).
When I run (on local jenkins)
java -jar jenkins-cli.jar -s http://10.23.0.6:8080/ help --username my_usr --password my_pwd
it gives a valid output.

When I run (on remote jenkins)
java -jar jenkins-cli.jar -s http://us.astorex.com:4555/ help --username my_usr --password my_pwd
it crashes. output attached.

There are no any issues with version 1.534, reverted to it.
