io.github.congcoi123:tenio (maven):  TenIO is a java NIO (Non-blocking I/O) based server specifically designed for multiplayer games. It supports UDP and TCP transports which are handled by Netty for high-speed network transmission. It uses MsgPack for compressing data so that can be transferred quickly through the network. This framework can help you quickly create a game server or integrate it into your system.
