> Looking into the source code this seems to be because the fallback endpoint for getting the OpenJDK census is used, a URL, which is not a valid path (at least not on Windows), so the check to see if we're dealing with a path or not fails when parsing the path.
> This PR switches to a regular expression for checking whether the endpoint is a URL or not (by checking if it starts with `http(s)://`).
