No idea to be honest.

:/

I tried replacing WarmRoast, replacing the server, tested in another system, and i get always the same error.
Also, i downloaded Warmroast from WarmRoastSetup repo, from Robotia.

[sk89q]

OpenJDK or Oracle JDK? Version of Java? for the JDK & the JRE that you run the server under

[Eufranio]

Oracle JDK, version 1.8-u101, same for JRE.

Blaming xKit now, after removing it, WarmRoast worked: caoli5288/xKit#5
