Whitelist not functioning correctly

[msinfo32github]

Using the latest build (Link) and using a whitelist.json in this format (fake UUID)

Whitelist does not function correctly and any player(s) can join the Limbo server. The server is configured as a back-end server in Velocity.

whitelist.json:

[
  {
    "uuid": "069a79f4-44e9-4726-a5be-fca90e38aaf5",
    "name": "Notch"
  }
]
