Pull request: #543:
CommandRegistry interface has been removed two methods:

1. execute(CommandSession session, String command, String[] args)
   You should implement instead invoke(CommandSession session, String command, Object... args)

2. CmdDesc commandDescription(String command)
   You should implement instead CmdDesc commandDescription(List<String> args) , where args.get(0) is equal command.
