I set up a Spigot server on my PC, created from the latest BuildTools. There are no errors on startup, but I can't log in due to a Java security exception.
I've tried updating Java to the latest release, creating a clean server directory, running both CraftBukkit and Spigot builds, with the matching version of Minecraft. I've connected to both 127.0.0.1 and localhost, with and without specifying the port. In all cases the error is the same. This only happens with my local server- I'm able to log in to multiple remote servers just fine.
Client message:
Failed to connect to the server
Disconnected
