I've tried both the latest stable and experimental releases. I'm not going to provide a full trace, but it seem the most important exception part is:
SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container
java.lang.UnsupportedOperationException: Position.source
I get this whenever I try "Run in Sandbox" or "Publish into Tournament" with the default "Hello World" bot code.
I tried to make sure to launch the game from both a regular cmd.exe and an elevated one... Just in case.
Any ideas? I'm going to try to dig into it, but being a complete Scala/Akka novice, it could take me a while.
I have VMware Workstation installed, and do notice that it looks like Scalatron fires up its port on one of the virtual interfaces created. I disabled that NIC, but even if Scalatron fired up a connection on a "better" IP, that didn't help. Even trying to shut down the Windows firewall didn't help.
I'm running this with Java 1.8, so my next attempt will be to perhaps try 1.6 or 1.7.
