看到非常奇怪的行为。我的代码执行良好，但不确定发生了什么，方法正在调用其他方法但没有调用其他方法（我看不到其他方法第一行中的日志）

代码 -

  public static void startMicroSessionTimer(TimerName timerName, Data Data) {
        logger.debug("Starting a micro-timer for timer name: " + timerName);
        //Start a micro timer to process the soap response in worker thread
        SipApplicationSession applicationSession = Util.getAppSession((String)Data.get(DataAttribute.ID));
        Util. AbcTimer (applicationSession, 1L, timerName.getTimerName());
  }


public static void AbcTimer(SipApplicationSession appSession,
            long timeInMillies, String timerName) {

        logger.debug("Inside AbcTimer”);
        //Some Logic
}

日志 -

在 Thread 的上述行之后无法看到任何日志jaxws-engine-1-thread-12。根据日志，该日志Inside AbcTimer应该在被调用方法（即 AbcTimer）的开头出现。没有发生异常。

我也采用了上面发布的 ThreadDump。

不确定，但认为这是特定于机器的问题。也谷歌它，看到其他人也发生了这种类型的问题，但我没有得到解决方案。

使用以下 JRocket 版本
