Minecraft Forge Server Refuses to Start with Start.Command File

[Noeisdas]

First post here.

 

A recurring issue with Forge servers for me, regardless of my mods, client or server, is that I can never get the universal jar to launch.  I have used the installer for version 1.12.2 2808 and followed all the customary procedures.  If I just double click the jar, it opens fine, but using the command file I cannot seem to get it to work.  I have also tried to run without any mods in the mods folder but with the same result every time.  I desire to use start.command so I can run Forge with JVM arguments in order to allocate more RAM.

 

The error appearing is as follows:

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

(I am sorry, I can't figure out how to use spoilers)

 

I have read the EAQs and the response to this problem (the cannot be cast problem) is that I ought to be running Java 8.  I am running Update 201 Java 8 for Mac OS 10.13.6 and have updated, restarted, and tried all this today as well as in the past.  I have even gone as far as to use iTerm.  

Any help?  

 

Logs are attached.  They probably contain too much information from the successful, non-start.command file runs but I hope what I have attached is helpful.  Let me know please if any other information is required.  Thanks so much.

This is indicative of trying to launch Forge with Java 9 or later, you need to use Java 8 specifically.
