Although the transactionId is also provided in the {@link #complete(Command)} callback, it is passed in here as wellso that an implementation can ensure that the {@link Command} is fully populated in orderto persist if required.
One case where this may be supported (for example, by the CommandServiceJdo implementation) is to flush still-running {@link Command}s to the database on-demand.

        final CommandService commandService = getServiceOrNull(CommandService.class);
        if(commandService == null) {
            return;
        } 
        final Command command = commandContext.getCommand();
        commandService.startTransaction(command, transactionId);
    }




    /**
     * @return - the service, or <tt>null</tt> if no service registered of specified type.
