java.lang.IllegalArgumentException: Non-positive period.

出错代码：

timer = new Timer();
timer.schedule(new MQConnectionTimerTask(), new Date(), 0);

错误信息：

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

原因：
在项目中用到了TimerTask时间调度器，如果调度间隔时间为0的时候，则会发生错误:java.lang.IllegalArgumentException: Non-positive period.，必须要设置大于0 的数。

解决方案：
调度间隔时间值确保大于0，如：

timer = new Timer();
timer.schedule(new MQConnectionTimerTask(), new Date(), 1 * 60 * 1000);
