有两个小疑点，请大家帮下忙~（其实都不算什么有关问题）

[color=#FF0000]问题1：[/color]请看下面注释，CMD/C 是啥东西？

public class OSExecute {    public static void command(String command){        boolean err = false;        try{            Process process = new ProcessBuilder(command.split(" ")).start();            BufferedReader results = new BufferedReader(                    new InputStreamReader(process.getInputStream()));            String s;            while((s = results.readLine()) != null){                System.out.println(s);            }                        BufferedReader errors = new BufferedReader(                    new InputStreamReader(process.getErrorStream()));            while((s = errors.readLine()) != null){                System.err.println(s);                err = true;            }        }catch(Exception e){            if(!command.startsWith("CMD/C")){  //这里的CMD/C是什么意思，为什么要以这个结尾？                command("CMD/C " + command);            }else{                throw new RuntimeException();            }        }        if(err){            throw new OSExecuteException("Errors executing " + command);        }    }}
