Server crash

Hello, there.

Since I installed Decocraft and it's dependency (PTRlib), my server always crashes while starting.

Here follows the crash report: https://mclo.gs/MMceT7d

I tried both of the most recent Decocraft versions (2.6.3 and 2.6.2 [the crash report refering to the 2.6.2 testing]).

Does anyone know what seems to be the problem? I'd really like to play with Decocraft installed

I did it but there seams to be a problem still!

Here's the log: https://mclo.gs/YuxvIOy

It has finally worked, thanks
