      To see the issue
      i) create an interval timer to expire in 5 secs then repeat every 2 hours.
      ii) let it expire
      iii) restart JBoss
      iv) observer timer expires again.

      This can be achieved using the timer project in the ejbTutorial1_1_0 from http://www.jboss.org/ejb3/docs.html
      Just replace ExampleTimerBean.java with the attached version.

      If you restart JBoss after an interval timer has expired it re-expires. This means the timer is, in effect, called every timer the server is restarted.

      The spec [section 18.4.2] states what should happen between a server crash and a restart - "Any interval timers that have expired during the intervening time must cause the timeout callback method to be invoked at least once upon restart."
