I'm also getting "ERROR:java.security.cert.CertPathValidatorException.." I can't read anything past that. I'm trying to use the local network and from reading the doc I need a VPN?
I honestly don't get why you would build this app at all. I've struggled for years to control my ISY device because Java is dead and awful to use. Why in the world would you not just build a robust web application that would work on all oses?
