BungeeComponentSerializer doesn't work on Java 16

[astei]

Unclear what you're referring to here. The toString() output looks correct to me - the BungeeCord text serializer works by "laundering" an Adventure Component such that when serialized by ComponentSerializer.toString() it will produce the Adventure component.

Does the output of GsonComponentSerializer.gson().serialize() on the original component and ComponentSerializer.toString() on the BaseComponent returned by BungeeComponentSerializer disagree with each other?

        System.out.println(GsonComponentSerializer.gson().serialize(input.getMessage()));
        BaseComponent[] components = BungeeComponentSerializer.get().serialize(input.getMessage());
        System.out.println(ComponentSerializer.toString(components));

As an aside, it may be a good idea to override AdapterComponent#toString, to ease future debugging on the matter and reduce confusion arising from the toString output.

This is caused by the bungeecord-chat library using java.awt.Color internally.

This was already fixed in 1129e6e in December 2020, stop using severely outdated versions of -platform.
