Sorry for not making this issue in ecoron/SimpleAuth. For some reason the issue button is not available there.
Anyway your 1.8.0 fork of SimpleAuth crashes when one player above max players joins (they get kicked with "server full"). Note that Shoghi made some code changes to the UUID; so we may need a new approach for fixing SimpleAuth and PurePerms:

The error that occurs when you have 2/2 players in server and attempt to connect a third player is:
I wonder if the uuid data is null because the player has already been kicked for "server full" before SimpleAuth gets a chance to run.
