I'm running Jenkins 2.361.1 on CentOS 7 with java-11-openjdk. I had to connect a Windows Server 2012 R2 node, last time I used java web start but in this case the option is not available anymore. So I need to use agent with winsw wrapper (as explained here setting up java 11 also on windows server). But the command doesn't work.

I have this handshake error and I don't know how to fix. I see the POST request from controller httpd access.log. Any suggestion about it? Thanks!
