Hi everybody !
I can't use this awesome plugin on my new server as adding it prevents the server from starting...
Two errors messages show up each time :

• ERROR]: Encountered an unexpected exception
• WARN Unable to instantiate org.fusesource.jansi.WindowsAnsiOutputStream

Could you help me, please ?

That error just means that the console does not support all features (like color).

Is there any other error? Does the error still occur if you remove TerrainControl?

Thank you for your answer ;)
The error only occures with TerrainControl because removing the plugin makes everything ok.
I give you my logs and crash reports, maybe you will find something to help me :)

Might it be the same error as described here : https://hub.spigotmc.org/jira/browse/SPIGOT-677 ?
If it is, how can I deal with it ?

Yeah, based on your server log it is that error. Updating Spigot should fix it.

But I already have Spigot 1.8.3 R0.1, is there a latest version of Spigot than this ?

Yes, new builds of Spigot are posted almost daily, as you can see here. Although their version all starts with Spigot 1.8.3 R0.1, they have a different suffix. Use the /version command to see the exact version of your build. Re-run BuildTools to obtain a newer Spigot build.

Ok thank you very much it works all right !
