java.lang.IllegalArgumentException: Non-positive period.

在项目中用到了TimerTask时间调度器，如果调度间隔时间min 为0的时候，则会发生错误，必须要设置大于0 的数。

 

timer = new Timer();
final long min = configListenerTime*60*1000;
timer.schedule(new MQConnectionTimerTask(), min, min);

 

解决方案:

min 的值 确保大于0;

 

错误信息:

严重: Exception sending context initialized event to listener instance of class com.queuemanagerlistener.listener.MQConnectionStatusListener
