修改为:
protected static Pattern pattern = Pattern.compile("HTTP Simple Queue Service 
v(.+?)\\s(?:.+?)\\sQueue Name: (.+?)\\sMaximum number of queues: (\\d+)\\sPut 
position of queue \\((\\d+)\\w+ lap\\): (\\d+)\\sGet position of queue 
\\((\\d+)\\w+ lap\\): (\\d+)\\sNumber of unread queue: (\\d+)");
主要当put第二轮的时候\\d+nd 而原来在正则还是匹配 
\\d+st改成 (\\d+)\\w+:
