> reschedule method of Timer utility in Muse will give illegal state exceptions
> -----------------------------------------------------------------------------
>
> Key: MUSE-154
> URL: http://issues.apache.org/jira/browse/MUSE-154
> Project: Muse
> Issue Type: Bug
> Components: Utilities - General, QName, and XML
> Affects Versions: 2.0.0, 2.1.0
> Environment: any
> Reporter: Mohammad Fakhar
> Assigned To: Dan Jemiolo
> Priority: Minor
> Fix For: 2.1.0
>
>
> The reschedule method of Timer utility gives the following error upon
> execution:
> java.lang.IllegalStateException: Task already scheduled or cancelled
> at java.util.Timer.sched(Timer.java:331)
> at java.util.Timer.schedule(Timer.java:157)
> Here is the scenario:
> 1) I schedule a resource for termination at time X using the scheduled life
> time capability.
> 2) 5 seconds later, I re-schedule the same resource for termination at time Y
> (where Y is > X).
> 3) The lifetime capabilites use the Timer utility underneath the covers and
> upon rescheduling, the reschedule
> method is called in SimpleScheduledTermination implementation:
> _terminationTimer.reschedule(time);
> 4) The reschedule method cancels the task, creates a new instance of a timer
> and schedules the SAME instance of the task with the new timer:
> Timer.reschedule {
> ............
> cancel();
> _timer = new java.util.Timer();
> schedule(whenToFire);
> }
> Timer.schedule {
> ..........
> _timer.schedule(_task, whenToFire);
> }
> 5) Now, java.util.Timer doesn't allow you to schedule the same instance of a
> previously cancelled task EVEN with a new timer instance (I experimented with
> it on the side). This is not explicit in the jdk javadoc, but it won't allow
> you to do this. Not sure if this should be a jdk bug or not, but I thought I
> would get it documented here at least.
> 6) this problem will surface whenever Muse implements the WS-N Renew function.
