Решено ProtocolSupport 4.28 чрезмерно много жрет ОЗУ

[Crosstwinz]

Дело вот в чем, я ставлю ProtocolSupport версии 4.28 на чистый spigot сервер версии 1.12.2 (стандартные настройки сервера стоят по дефолту за исключением отключенного Ада и Края). Когда я включаю сервер, во время непосредственного включения плагина расход ОЗУ превышает 1 ГБ без онлайна и других плагинов (без этого плагина расход ОЗУ ядром стандартное в пределах 200-250 МБ)!! Ошибок в логах нет, использую Java версии 8 build 51 (x64). В стандартной сборке сервера для выживания этот плагин также себя ведет.

Параметры запуска сервера следующие:

java -server -XX:+UseG1GC -Xmx2G -jar spigot.jar

У меня возникала идея заменить ProtocolSupport плагинами ViaRewind и ViaBackward в связке с ViaVersion, но тогда я не могу блокировать подключение игроков версий 1.7.x (как blockversion для ProtocolSupport)

Помогите разобраться.

Полный лог работы сервера:

БИНГО!!!! Я придумал, как грамотно заменить ProtocolSupport! Буду использовать следующие плагины: ViaRewind и ViaBackward в связке с ViaVersion. Но при этом, чтобы клиенты версий с 1.7.x не смогли подключаться к серверу, игроки буду проходить через bungeecord (а ведь он пропускает версии, начиная с 1.8 и выше без всяких дополнительных плагинов не борту), а уже потом попадать на сам серв. Тему можно считать закрытой.
