setTCPNoDelay inaccessible

[Lloren]

I am developing a game off this server code and ran into TCP buffering (Nagle's algorithm) while I was trying to keep my clients updated at 90 tick.

I hacked in to hardcode setTcpNoDelay to true on the client socket that was created. (WebSocketServer.java:309)

I can create a pull request but I am not sure how much you would want that universality architected (setting of Socket or SocketChenel options)
