Parallel test execution not working in v3

[jkretsch]

Description of the bug/issue

I have Nightwatch config like so ...

			test_workers: {
				enabled: true, // run tests in parallel (Jenkins server has 4 cores)
				workers: "auto", // specify number of parallel threads; default is 'auto'
			},

but execution is not working in Nightwatch v3. It runs perfectly in Nightwatch v2.

Steps to reproduce

1. Go to '...'
2. Click on '...'
3. Scroll down to '...'
4. See error

Here's the command line along with the output ...

C:\git\portal-ui-tests>node nightwatch -e firefox_selenium_parallel tests/newyork_tests.js tests/colorado_tests.js --verbose

That's it. No other output and the tests never run.

Issue resolved. I was running on Oracle JDK version 8 and it seems Nightwatch v3 does not play nicely with that version of Java. I replaced my Oracle JDK with the latest Adoptium version and now parallel test execution in Nightwatch v3 is working as expected.
