---------------------------------------------------------------------------

by the way i have no idea for this line

(() -> player.closeNetConnection(), 20000);         ------> closeNetConnection()   this error          

and this line

return player.getClient().getConnection().getSocketChannel().socket().getInetAddress().getHostAddress();

getSocketChannel ----> this error

 

I using l2jserver Beta

core. 6670
