I have no mods, no plugins, nothing installed that I know of. It's fresh. If it helps, my .bat file is this;
java -XX:PermSize=128M -XX:MaxPermSize=256M -Xms1G -Xmx2G -jar cauldron-1.6.4-1.965.21.204-server.jar
PAUSE
Also, so apparently it refused to launch without Java 8, even though Forge breaks with java 8? So I had to install both- if that makes a difference.
