Question

我有这个由其他人开发的Java Swings应用程序，它延迟了Windows Server 2008 r2 32 Bit上某些进程的执行，但它在Windows XP 32＆amp; Windows 7 32位。我已经确认该应用程序运行在与Windows XP和Windows XP相同的JRE（32位版本）上。 Windows 7。

注意：我已经在Windows XP和Windows 7中测试了延迟应用程序，并且没有遇到过这样的问题。但是Windows Server 2008 r2（32位操作系统）在应用程序日志中会出现延迟。

以下是延迟交易的代码：

private Thread TID;       // The Consumer thread
private Object q[];       // Queued Values for thread
private int nQueue;       // Number of items in the Queue
private int dataStatus;   // Status of the Queue
private long timeout;

private String myName;
private int MaxSize;

// legal Queue status values
final static int NONE = 0;     // No data available
final static int NEW = 1;      // New data available
final static int OVERRUN = 2;  // Data overrun (queue overflow)
final static int SHUTDOWN = 3; // Data stream shutdown


DataItem(Thread t, String name, int Q, long timeo)
{
    q = new Object[Q];
    nQueue = 0;
    TID = t;
    timeout = timeo;
    dataStatus = NONE;
    myName = name;
    MaxSize = Q;
}

DataItem(Thread t, String name, int Q)
{
    this(t, name, Q, 10);
}

/** shorter version for a queue size of two (2) */
DataItem(Thread t, String name)
{
    this(t, name, 2, 3000);
}



 synchronized Object fetch(Trace log) throws DataStreamOverrun,
                                   DataStreamShutdown,
                                   DataStreamTimeout
{
    Object r = null;

    /* If nothing is waiting, we sleep.*/
    if (dataStatus == NONE)
    {
        log.event("dataStatus :"+dataStatus);
        try
        {
            long was = System.currentTimeMillis();
//              wait();
            log.event("was :"+was);
            wait(timeout);
            log.event("timeout :"+timeout);
            if ((System.currentTimeMillis() - was) >= timeout)
                throw new DataStreamTimeout();
        }
        catch (InterruptedException e){
            log.event("SHUTDOWN :"+SHUTDOWN);
            dataStatus = SHUTDOWN; 
        }
    }

    if(nQueue > 0)
    {
        log.event("--------- " + "Version ( " + MyPin.getVersion() +
                " ) ---------");
        log.event("Reading msg from stream : " + myName +
                " size(" + nQueue + "/" + MaxSize + ")");
    }
    /* Data (or Status) has arrived so dispatch it. */
    switch (dataStatus)
    {
        case NONE:
            break;
        case NEW:
            r = q[0];
            System.arraycopy(q, 1, q, 0, q.length - 1);
            nQueue--;
            break;
        case OVERRUN:
            dataStatus = NEW; // Next call will get the data
            throw new DataStreamOverrun();
        case SHUTDOWN:
            throw new DataStreamShutdown();
    }
    if (nQueue == 0)
      dataStatus = NONE;
    return r;
}

Java应用程序在Windows 7，Windows XP中运行良好，但在Windows 2008 Server r2中运行良好
