EWG DatatypeConverter error on load

[Zakra]

Plugin version: 8.0.0 PRE-RELEASE 4

Spigot username: xeradam

Issue: I get an error when I try to load the plugin.

Link to settings file (world-settings.json, possibly also biome settings if you have created your own): I can't possibly add something here since the logs won't even generate since the plugin won't load.

Link to error log/crash log: https://pastebin.com/SwGFRaWv (Btw Hastebin deletes the logs after some time passes, pastebin don't)

Fixed the issue myself, after some research I found out that this plugin won't run in Java 9, so I downgraded in Java 8 and it worked perfectly! :D
