Execute Third-Party Jar From Command Line, Flag To Ignore SSL Issues?

Execute Third-Party Jar From Command Line, Flag To Ignore SSL Issues?

I'm executing the W3C CSS validator jar from the command line, built from
the latest-available source. Exceptions are raised when the jar requests
some HTTPS urls.
Some HTTPS urls are fine, others are not. Of those that cause exceptions
to be raised of which I am aware (just one), the SSL cert appears to be
fine when requesting the relevant URL in Chrome.
I call the CSS validator as follows:
java -jar css-validator.jar "https://example.com/"
And get the following error output:

I'd ideally like to ignore absolutely all such SSL errors that could be
raised when executing this jar from the command line using something along
the lines of:
java -ignore-all-of-these-ssl-errors-please -jar css-validator.jar
"https://example.com/"
Clearly ignore-all-of-these-ssl-errors-please is not a valid command line
flag.
Is there a flag that will do this?
