Hi, as Paper is soon to require Java 16, and Mojang have started using Java 16 with snapshot 21w19a, I decided to update my server to use the same. Using Paper or Spigot 1.16.5 and Parties 3.0.4 I get the error below on startup

[23:51:59] [Server thread/INFO]: [Parties] Enabling Parties v3.0.4
[23:51:59] [Server thread/ERROR]: Error occurred while enabling Parties v3.0.4 (Is it up to date?)

Hello,
Java 16 is not supported due to problems with reflections, used in external library loading. Right now its not possible to support it, let's see in the future if Bukkit/BungeeCord will manually support loading of external libraries or I find a way to load them correctly in other ways :)
