Bukkit

Good afternoon.
I am trying to create a world with Island World Generation
For the server, I use the kernel Thermos
can be downloaded from here: http://cyberdynecc.github.io/Thermos/

I use: MC 1.7.10 Update - Floating Island Generator 5.1 (CB 1.7.9-R0.2)

Generating the world according to the instructions

But I get this error:

Link to download the server for testing: https://drive.google.com/file/d/0BwvDHkPm5SFASXRMUUpiY3o0YVU/view?usp=sharing
I use java 8, use the java 7 I can not because it is not supported by the kernel.

Please tell me what the error might be?
What version of the plugin I need to use the creation of the world it would work?

Sorry for my english, I'm using a translator

Server Version 1.7.10

How can I disable the creation of water and lava everywhere except the islands in the form of beach, where in the middle of the lake?
Water and lava that is created in the form of blocks and bottled in the world is very much loaded server
