I ran into the following issue where Quartz crashed with the under furnished exception. On debugging the issue, I came across the following line of code in

[b]JobStoreSupport.recoverMisfiredJobs(
        Connection conn, boolean recovering)
[/b]
  
 [i] if(trig.getNextFireTime().getTime() < earliestNewTime)
             earliestNewTime = trig.getNextFireTime().getTime();[/i]

The exception arises because in the method, [i] doUpdateOfMisfiredTrigger(conn, null, trig, false, STATE_WAITING, recovering)[/i], called just prior to the execution of the above line, trig.nextFireTime is set to null at some point in the stack.

So a simple fix would be a NULL check on[i] trig.getNextFireTime()[/i] before [i]getTime()[/i] is called in the if clause [i]if (trig.getNextFireTime().getTime() < earliestNewTime)[/i]

Please do let me know your thoughts on the same.

-thanks
