我的java难道是盗版吗（调用有返回值的函数无响应）

Question

boolean flag = pcSystem.returnTenderResult(bidDocu,tenderDocu);

我在自定义pcSystem类中调用一个具有boolean返回值的函数returnTenderResult（synchronized）

这条语句的上一条语句都会执行，而returnTenderResult内方法一定概率上不执行

（方法内的第一条语句都没有执行，还不涉及方法内具体逻辑），系统涉及了多线程，

这是为什么啊

 public synchronized boolean reviewOtherCommForhelpTask(BidDocu bidDocu,TenderDocu tenderDocu) throws IOException{//评审其他社区寻求帮助任务的时间及资源
        boolean flag = false;
//      ====================================
        Date nowDate = new Date();

        String log = "reviewOtherComm,当前用时"+(nowDate.getTime()-TimerManager.getTimerStamp()[0])+
                "ms"+System.getProperty("line.separator");
        TakeNotes.recordLogs(commid, log);
//      ====================================
        if(bidDocu.getFid()<=CommMessageManager.pcFid){
            //PC
//          ====================================
                    nowDate = new Date();
                    log = "check Pc Task,当前用时"+(nowDate.getTime()-TimerManager.getTimerStamp()[0])+
                            "ms"+System.getProperty("line.separator");
                    TakeNotes.recordLogs(commid, log);
//                  ====================================
            flag = pcSystem.returnTenderResult(bidDocu,tenderDocu);
        }else {
            //Robot
//          ====================================
                    nowDate = new Date();
                    log = "check Robot Task,当前用时"+(nowDate.getTime()-TimerManager.getTimerStamp()[0])+
                            "ms"+System.getProperty("line.separator");
                    TakeNotes.recordLogs(commid, log);
//                  ====================================
            flag = robotSystem.returnTenderResult(bidDocu,tenderDocu);
        }
        return flag;
    }

 public synchronized boolean returnTenderResult(BidDocu forHelpBidDocu,TenderDocu tenderDocu) throws IOException{
        Date nowDate = new Date();
        String log;
        boolean flag = false;
//      =================================
        nowDate = new Date();
        log = "returnTenderResult,当前时间"+
                (nowDate.getTime()-TimerManager.getTimerStamp()[0])+"ms"+
                    System.getProperty("line.separator");
        TakeNotes.recordLogs(commid,log);
//      =================================
}

是不是多线程的问题，执行顺序是怎么样的
