Yes. It's a bad example, as the only example URL that should ever be used is example.com.   Not sure what to say. Forge rrequires Java 8 anyways, so just compile with Java 8?

I continued poking around this morning, removing the 'comment out' and instead replacing the URL with a more complete version (updateJSONURL="https://www.myurl.me/") which threw this error:   Caused by: java.security.cert.CertificateException: No subject alternative DNS name matching www.myurl.me found. Minecraft did load, but with the above error. Mods.toml is created by Forge, yes?  Is myurl.me listed merely as an example?  Sorry if this is a stupid question, I've been learning Java for about 12 minutes now, so I'm a little short on experience.   I guess this resolves the first part of my issue, as runClient succeeds despite the errors.  Thank you for that.  Still hopeful for some wisdom or direction on attempting to recompile the mod from JDK 1.6 up to Java 1.8.  Perhaps a tutorial, video or some other instructional to succeed in this epic task? Many thanks, M

Sorry about that, I was looking at the main post in the link by DamnRelentless

Post the complete error output...
