Node not being registered to hub selenium 3.12.0 (Was passed main parameter '-role')

[Khoosham]

Meta -

OS:
Windows 10
Selenium Version:
3.12.0
Browser:
Chrome
Browser Version:
66.0.3359.139 (64-bit)

Expected Behavior -

Node should attach to hub as in selenium version 3.8.1.

Actual Behavior -

I am using selenium 3.8.1 version. i have made my own utility to start/stop hub and register node etc...
Currently i am using this command to register the node to the server and this works great.

String[] args = { "-role", "node", "-host", host, "-hub", hubURL, "-port", port };
GridNodeConfiguration gridNodeConfiguration = new GridNodeConfiguration();
 JCommander.newBuilder().addObject(gridNodeConfiguration).build().parse(args);

The issue i am having is that i have updated to 3.12.0 and the command above does not work.
i get the following error com.beust.jcommander.ParameterException: Was passed main parameter '-role' but no main parameter was defined in your arg class. Like you see above i have already defined the role as node but still the node wont attach. Any help regarding this please ? Thank you.

Please share the complete code, that you are using to start the node.

 

Thanks & Regards
