I am trying to run the Monster FTB server and I keep getting the same error on two different local machines.
The first machine is running Debian with Oracle Java, not OpenJDK.
The second machine is running Windows 8.1 with the latest Java.
I have tried this guide for Linux - http://forum.feed-the-beast.com/threads/johnleys-fast-and-easy-server-setup-guide.1290/
and I have tried running the batch file on my Windows machine and I get the same error message on each machine.
I have been running servers for years and haven't had this much trouble getting one to run. Thank you.
