Other

It seems that specifically what breaks is fetching the TPS. Based on the code TAB is expecting and array of Doubles but instead gets just a Double.

TAB code:

Object server = Bukkit.getServer().getClass().getMethod("getServer").invoke(Bukkit.getServer());
recentTps = ((double[]) server.getClass().getField("recentTps").get(server)); // This line errors
