Java使用ProcessBuilder创建子进程出现错误：CreateProcess error=87

Exception occurred executing command line. 
Cannot run program... CreateProcess error=87, The parameter is incorrect

网上说的错误原因是CLASSPATH过长，但我测试发现，还有一种原因


根据ProcessBuilder的构造器，

/**
Constructs a process builder with the specified operating system program and arguments. This is a convenience constructor that sets the process builder's command to a string list containing the same strings as the command array, in the same order. It is not checked whether command corresponds to a valid operating system command.Parameters:
command a string array containing the program and its arguments
**/
public ProcessBuilder(String... command) {
}

对于command参数，首个参数是命令，如果使用的是相对路径，该命令还会从操作系统的PATH环境变量中去搜寻。
如果默认不是.bat或者.exe后缀，比如（.cmd）,那么需要显示加上后
